Towards solving these current challenges, in the present work, we detail a low temperature solution-based approach to produce Bi2Te3-Cu2-xTe nanocomposites with improved thermoelectric performance. Our approach consists in combining proper ratios of colloidal nanoparticles and to consolidate the resulting mixture into nanocomposites using a hot press. The transport properties of the nanocomposites are characterized and compared with those of pure Bi2Te3 nanomaterials obtained following the same procedure. In contrast with most previous works, the presence of Cu2-xTe nanodomains does not result in a significant reduction of the lattice thermal conductivity of the reference Bi2Te3 nanomaterial, which is already very low. However, the introduction of Cu2-xTe yields a nearly threefold increase of the power factor associated to a simultaneous increase of the Seebeck coefficient and electrical conductivity at temperatures above 400 K. Taking into account the band alignment of the two materials, we rationalize this increase by considering that Cu2-xTe nanostructures, with a relatively low electron affinity, are able to inject electrons into Bi2Te3, enhancing in this way its electrical conductivity. The simultaneous increase of the Seebeck coefficient is related to the energy filtering of charge carriers at energy barriers within Bi2Te3 domains associated with the accumulation of electrons in regions nearby a Cu2-xTe/Bi2Te3 heterojunction. Overall, with the incorporation of a proper amount of Cu2-xTe nanoparticles, we demonstrate a 250% improvement of the thermoelectric figure of merit of Bi2Te3.","lang":"eng"}],"_id":"9304","intvolume":"       418","status":"public","main_file_link":[{"url":"https://ddd.uab.cat/record/271949","open_access":"1"}],"publication_status":"published","ec_funded":1,"title":"Influence of copper telluride nanodomains on the transport properties of n-type bismuth telluride","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","oa":1,"citation":{"mla":"Zhang, Yu, et al. “Influence of Copper Telluride Nanodomains on the Transport Properties of N-Type Bismuth Telluride.” <i>Chemical Engineering Journal</i>, vol. 418, no. 8, 129374, Elsevier, 2021, doi:<a href=\"https://doi.org/10.1016/j.cej.2021.129374\">10.1016/j.cej.2021.129374</a>.","short":"Y.

In the present work, we investigate the effect of different dopants to enhance the Cu2−xS performance and also its thermal stability. Among the tested options, Pb-doped Cu2−xS shows the highest improvement in stability against sulfur volatilization. Additionally, Pb incorporation allows tuning charge carrier concentration, which enables a significant improvement of the power factor.

Here, we promoted the TE performance of n-type SnSe polycrystals through bandgap engineering and vacancy compensation. We found that PbTe can significantly reduce the wide bandgap of SnSe to reduce the impurity transition energy, largely enhancing the carrier concentration. Also, PbTe-induced crystal symmetry promotion increases the carrier mobility, preserving large Seebeck coefficient. Consequently, a maximum ZT of ∼1.4 at 793 K is obtained in Br doped SnSe–13%PbTe. Furthermore, we found that extra Sn in n-type SnSe can compensate for the intrinsic Sn vacancies and form electron donor-like metallic Sn nanophases. The Sn nanophases near the grain boundary could also reduce the intergrain energy barrier which largely enhances the carrier mobility. As a result, a maximum ZT value of ∼1.7 at 793 K and an average ZT (ZTave) of ∼0.58 in 300–793 K are achieved in Br doped Sn1.08Se–13%PbTe.

However, solution synthesis generally involves the presence of additional molecules or ions belonging to the precursors or added to enable solubility and/or regulate nucleation and growth. These molecules or ions can end up in the particles as surface adsorbates and interfere in the material properties. This work demonstrates that ionic adsorbates, in particular Na⁺ ions, are electrostatically adsorbed in SnSe particles synthesized in water and play a crucial role not only in directing the material nano/microstructure but also in determining the transport properties of the consolidated material. In dense pellets prepared by sintering SnSe particles, Na remains within the crystal lattice as dopant, in dislocations, precipitates, and forming grain boundary complexions. These results highlight the importance of considering all the possible unintentional impurities to establish proper structure-property relationships and control material properties in solution-processed thermoelectric materials.","lang":"eng"}],"status":"public","article_processing_charge":"Yes (via OA deal)","issue":"52","publication":"Advanced Materials","publisher":"Wiley","volume":33,"day":"29","keyword":["mechanical engineering","mechanics of materials","general materials science"],"type":"journal_article","corr_author":"1","quality_controlled":"1","article_type":"original","date_created":"2021-10-11T20:07:24Z","year":"2021","citation":{"mla":"Liu, Yu, et al. “The Importance of Surface Adsorbates in Solution‐processed Thermoelectric Materials: The Case of SnSe.” <i>Advanced Materials</i>, vol. 33, no. 52, 2106858, Wiley, 2021, doi:<a href=\"https://doi.org/10.1002/adma.202106858\">10.1002/adma.202106858</a>.","ieee":"Y.

They control and direct nanocrystal syntheses and provide colloidal stability. Bound ligands also affect the nanocrystals’ chemical reactivity and electronic structure. Surface chemistry is thus crucial to understand nanocrystal properties and functionality. Here, we investigate the synthesis of metal oxide nanocrystals (CeO2-x, ZnO, and NiO) from metal nitrate precursors, in the presence of oleylamine ligands. Surprisingly, the nanocrystals are capped exclusively with a fatty acid instead of oleylamine. Analysis of the reaction mixtures with nuclear magnetic resonance spectroscopy revealed several reaction byproducts and intermediates that are common to the decomposition of Ce, Zn, Ni, and Zr nitrate precursors. Our evidence supports the oxidation of alkylamine and formation of a carboxylic acid, thus unraveling this counterintuitive surface chemistry.","lang":"eng"}],"status":"public","publication_status":"published","file":[{"date_created":"2022-03-02T15:33:18Z","file_name":"2021_JACSAu_Calcabrini.pdf","relation":"main_file","content_type":"application/pdf","date_updated":"2022-03-02T15:33:18Z","creator":"cchlebak","success":1,"checksum":"1c66a35369e911312a359111420318a9","file_size":1257973,"access_level":"open_access","file_id":"10807"}],"volume":1,"keyword":["general medicine"],"day":"22","page":"1898-1903","type":"journal_article","article_processing_charge":"Yes (via OA deal)","issue":"11","publication":"JACS Au","publisher":"American Chemical Society","acknowledgement":"This work was financially supported by IST Austria and the Werner Siemens Foundation.

This new doping strategy enables the adjustment of the density of charge carriers between 1019 and 1020 cm–3, and it may serve as a general strategy for doping other nanocrystal-based semiconductors.","lang":"eng"}],"intvolume":"         6","article_processing_charge":"Yes (via OA deal)","publisher":"American Chemical Society","issue":"2","publication":"ACS Energy Letters","day":"20","page":"581-587","volume":6,"type":"journal_article"},{"isi":1,"department":[{"_id":"MaIb"}],"doi":"10.1021/acsami.0c04331","publication_identifier":{"eissn":["19448252"]},"language":[{"iso":"eng"}],"external_id":{"pmid":["32437128"],"isi":["000542925300032"]},"month":"06","scopus_import":"1","oa_version":"Submitted Version","date_published":"2020-06-17T00:00:00Z","author":[{"first_name":"Yu","full_name":"Zhang, Yu","last_name":"Zhang"},{"id":"2A70014E-F248-11E8-B48F-1D18A9856A87","last_name":"Liu","full_name":"Liu, Yu","first_name":"Yu","orcid":"0000-0001-7313-6740"},{"full_name":"Xing, Congcong","last_name":"Xing","first_name":"Congcong"},{"last_name":"Zhang","full_name":"Zhang, Ting","first_name":"Ting"},{"last_name":"Li","full_name":"Li, Mengyao","first_name":"Mengyao"},{"first_name":"Mercè","full_name":"Pacios, Mercè","last_name":"Pacios"},{"first_name":"Xiaoting","full_name":"Yu, Xiaoting","last_name":"Yu"},{"last_name":"Arbiol","full_name":"Arbiol, Jordi","first_name":"Jordi"},{"first_name":"Jordi","last_name":"Llorca","full_name":"Llorca, Jordi"},{"first_name":"Doris","last_name":"Cadavid","full_name":"Cadavid, Doris"},{"orcid":"0000-0001-5013-2843","first_name":"Maria","last_name":"Ibáñez","full_name":"Ibáñez, Maria","id":"43C61214-F248-11E8-B48F-1D18A9856A87"},{"first_name":"Andreu","full_name":"Cabot, Andreu","last_name":"Cabot"}],"date_updated":"2025-04-24T11:49:17Z","project":[{"name":"ISTplus - Postdoctoral Fellowships","_id":"260C2330-B435-11E9-9278-68D0E5697425","call_identifier":"H2020","grant_number":"754411"}],"OA_place":"repository","ec_funded":1,"title":"Tin selenide molecular precursor for the solution processing of thermoelectric materials and devices","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","year":"2020","date_created":"2020-06-29T07:59:35Z","article_type":"original","quality_controlled":"1","corr_author":"1","oa":1,"citation":{"short":"Y.

Our strategy is based on the formulation of a molecular precursor that can be continuously decomposed to produce a SnSe powder or printed into predefined patterns. The precursor formulation and decomposition conditions are optimized to produce pure phase 2D SnSe nanoplates. The printed layer and the bulk material obtained after hot press displays a clear preferential orientation of the crystallographic domains, resulting in an ultralow thermal conductivity of 0.55 W m–1 K–1 in the direction normal to the substrate. Such textured nanomaterials present highly anisotropic properties with the best thermoelectric performance in plane, i.e., in the directions parallel to the substrate, which coincide with the crystallographic bc plane of SnSe. This is an unfortunate characteristic because thermoelectric devices are designed to create/harvest temperature gradients in the direction normal to the substrate. We further demonstrate that this limitation can be overcome with the introduction of small amounts of tellurium in the precursor. The presence of tellurium allows one to reduce the band gap and increase both the charge carrier concentration and the mobility, especially the cross plane, with a minimal decrease of the Seebeck coefficient. These effects translate into record out of plane ZT values at 800 K.","lang":"eng"}],"pmid":1,"main_file_link":[{"url":"https://ddd.uab.cat/pub/artpub/2020/235998/acsapplmaterinterfaces_a2020v12np27104pp.pdf","open_access":"1"}]},{"month":"11","oa_version":"Submitted Version","scopus_import":"1","language":[{"iso":"eng"}],"external_id":{"isi":["000581738300030"]},"OA_place":"repository","date_updated":"2025-04-24T11:53:45Z","date_published":"2020-11-01T00:00:00Z","author":[{"first_name":"Xiaoting","last_name":"Yu","full_name":"Yu, Xiaoting"},{"full_name":"Liu, Junfeng","last_name":"Liu","first_name":"Junfeng"},{"first_name":"Junshan","full_name":"Li, Junshan","last_name":"Li"},{"first_name":"Zhishan","last_name":"Luo","full_name":"Luo, Zhishan"},{"first_name":"Yong","full_name":"Zuo, Yong","last_name":"Zuo"},{"last_name":"Xing","full_name":"Xing, Congcong","first_name":"Congcong"},{"first_name":"Jordi","last_name":"Llorca","full_name":"Llorca, Jordi"},{"first_name":"Déspina","last_name":"Nasiou","full_name":"Nasiou, Déspina"},{"first_name":"Jordi","full_name":"Arbiol, Jordi","last_name":"Arbiol"},{"last_name":"Pan","full_name":"Pan, Kai","first_name":"Kai"},{"first_name":"Tobias","full_name":"Kleinhanns, Tobias","id":"8BD9DE16-AB3C-11E9-9C8C-2A03E6697425","last_name":"Kleinhanns"},{"full_name":"Xie, Ying","last_name":"Xie","first_name":"Ying"},{"full_name":"Cabot, Andreu","last_name":"Cabot","first_name":"Andreu"}],"department":[{"_id":"MaIb"}],"isi":1,"article_number":"105116","publication_identifier":{"issn":["2211-2855"]},"acknowledgement":"This work was supported by the European Regional Development Funds and by the Spanish Ministerio de Economía y Competitividad through the project SEHTOP, ENE2016- 77798-C4-3-R, and ENE2017-85087-C3.

In this work, we engineer a new electrocatalyst by incorporating phosphorous into a palladium-tin alloy and demonstrate a significant performance improvement toward EOR. We first detail a synthetic method to produce Pd2Sn:P nanocrystals that incorporate 35% of phosphorus. These nanoparticles are supported on carbon black and tested for EOR. Pd2Sn:P/C catalysts exhibit mass current densities up to 5.03 A mgPd−1, well above those of Pd2Sn/C, PdP2/C and Pd/C reference catalysts. Furthermore, a twofold lower Tafel slope and a much longer durability are revealed for the Pd2Sn:P/C catalyst compared with Pd/C. The performance improvement is rationalized with the aid of density functional theory (DFT) calculations considering different phosphorous chemical environments. Depending on its oxidation state, surface phosphorus introduces sites with low energy OH− adsorption and/or strongly influences the electronic structure of palladium and tin to facilitate the oxidation of the acetyl to acetic acid, which is considered the EOR rate limiting step. DFT calculations also points out that the durability improvement of Pd2Sn:P/C catalyst is associated to the promotion of OH adsorption that accelerates the oxidation of intermediate poisoning COads, reactivating the catalyst surface."}],"_id":"8189","intvolume":"        77","status":"public","main_file_link":[{"open_access":"1","url":"http://hdl.handle.net/2117/335346"}],"publication_status":"published","title":"Phosphorous incorporation in Pd2Sn alloys for electrocatalytic ethanol oxidation","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","oa":1,"citation":{"ama":"Yu X, Liu J, Li J, et al.

Core@shell NCs, in which one or more inorganic layers overcoat individual NCs, recently received significant attention due to their remarkable optical characteristics. Reduced Auger recombination, suppressed blinking, and enhanced carrier multiplication are among the merits of core@shell NCs. Despite their importance in device development, the influence of the shell and the surface modification of the core@shell NC assemblies on the charge carrier transport remains a pertinent research objective. Type-II PbTe@PbS core@shell NCs, in which exclusive electron transport was demonstrated, still exhibit instability of their electron \r\n ransport. Here, we demonstrate the enhancement of electron transport and stability in PbTe@PbS core@shell NC assemblies using iodide as a surface passivating ligand. The combination of the PbS shelling and the use of the iodide ligand contributes to the addition of one mobile electron for each core@shell NC. Furthermore, both electron mobility and on/off current modulation ratio values of the core@shell NC field-effect transistor are steady with the usage of iodide. Excellent stability in these exclusively electron-transporting core@shell NCs paves the way for their utilization in electronic devices.

Therefore, to exploit the full potential of nanocrystal building blocks to produce functional nanomaterials and thin films, a proper control of their surface chemistry is required. Here, we analyze how the ligand stripping procedure influences the charge and heat transport properties of sintered PbSe nanomaterials produced from the bottom-up assembly of colloidal PbSe nanocrystals. First, we show that the removal of the native organic ligands by thermal decomposition in an inert atmosphere leaves relatively large amounts of carbon at the crystal interfaces. This carbon blocks crystal growth during consolidation and at the same time hampers charge and heat transport through the final nanomaterial. Second, we demonstrate that, by stripping ligands from the nanocrystal surface before consolidation, nanomaterials with larger crystal domains, lower porosity, and higher charge carrier concentrations are obtained, thus resulting in nanomaterials with higher electrical and thermal conductivities. In addition, the ligand displacement leaves the nanocrystal surface unprotected, facilitating oxidation and chalcogen evaporation. The influence of the ligand displacement on the nanomaterial charge transport properties is rationalized here using a two-band model based on the standard Boltzmann transport equation with the relaxation time approximation. Finally, we present an application of the produced functional nanomaterials by modeling, fabricating, and testing a simple PbSe-based thermoelectric device with a ring geometry.","lang":"eng"}],"_id":"7467","intvolume":"         3","status":"public","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","file_date_updated":"2022-08-23T08:34:17Z","title":"Influence of the ligand stripping on the transport properties of nanoparticle-based PbSe nanomaterials","ec_funded":1,"quality_controlled":"1","article_type":"original","date_created":"2020-02-09T23:00:52Z","year":"2020","citation":{"chicago":"Cadavid, Doris, Silvia Ortega, Sergio Illera, Yu Liu, Maria Ibáñez, Alexey Shavel, Yu Zhang, et al. “Influence of the Ligand Stripping on the Transport Properties of Nanoparticle-Based PbSe Nanomaterials.” <i>ACS Applied Energy Materials</i>.

The ability to control the charge carrier transport in the colloidal NC assemblies is fundamental for altering their electronic and optical properties for the desired applications. Here we demonstrate a strategy to render the solids of narrow-bandgap NC assemblies exclusively electron-transporting by creating a type-II heterojunction via shelling. Electronic transport of molecularly cross-linked PbTe@PbS core@shell NC assemblies is measured using both a conventional solid gate transistor and an electric-double-layer transistor, as well as compared with those of core-only PbTe NCs. In contrast to the ambipolar characteristics demonstrated by many narrow-bandgap NCs, the core@shell NCs exhibit exclusive n-type transport, i.e., drastically suppressed contribution of holes to the overall transport. The PbS shell that forms a type-II heterojunction assists the selective carrier transport by heavy doping of electrons into the PbTe-core conduction level and simultaneously strongly localizes the holes within the NC core valence level. This strongly enhanced n-type transport makes these core@shell NCs suitable for applications where ambipolar characteristics should be actively suppressed, in particular, for thermoelectric and electron-transporting layers in photovoltaic devices.","lang":"eng"}],"pmid":1,"status":"public","publication":"ACS Nano","issue":"3","publisher":"American Chemical Society","article_processing_charge":"No","type":"journal_article","volume":14,"day":"24","page":"3242-3250"},{"department":[{"_id":"MaIb"}],"isi":1,"doi":"10.1021/acscatal.0c03210","publication_identifier":{"eissn":["2155-5435"]},"acknowledgement":"The authors also acknowledge financial support from the University Research Fund (BOF-GOA-PS ID No. 33928).

Yet, limited effort was devoted to understand the effect of ligand coverage and postsynthesis treatments on CO2 reduction, especially under industrially applicable conditions, such as at high currents (>100 mA/cm2) using gas diffusion electrodes (GDE) and flow reactors. In this work, Cu–Ag core–shell nanoparticles (11 ± 2 nm) were prepared with three different surface modes: (i) capped with oleylamine, (ii) capped with monoisopropylamine, and (iii) surfactant-free with a reducing borohydride agent; Cu–Ag (OAm), Cu–Ag (MIPA), and Cu–Ag (NaBH4), respectively. The ligand exchange and removal was evidenced by infrared spectroscopy (ATR-FTIR) analysis, whereas high-resolution scanning transmission electron microscopy (HAADF-STEM) showed their effect on the interparticle distance and nanoparticle rearrangement. Later on, we developed a process-on-substrate method to track these effects on CO2R. Cu–Ag (OAm) gave a lower on-set potential for hydrocarbon production, whereas Cu–Ag (MIPA) and Cu–Ag (NaBH4) promoted syngas production. The electrochemical impedance and surface area analysis on the well-controlled electrodes showed gradual increases in the electrical conductivity and active surface area after each surface treatment. We found that the increasing amount of the triple phase boundaries (the meeting point for the electron–electrolyte–CO2 reactant) affect the required electrode potential and eventually the C+2e̅/C2e̅ product ratio. This study highlights the importance of the electron transfer to those active sites affected by the capping agents—particularly on larger substrates that are crucial for their industrial application."}],"_id":"8926","intvolume":"        10","main_file_link":[{"url":"https://repository.uantwerpen.be/docman/irua/190103/173803.pdf","open_access":"1"}]},{"article_processing_charge":"Yes (in subscription journal)","publisher":"American Chemical Society","issue":"6","publication":"ACS Nano","page":"6572-6580","keyword":["colloidal nanoparticles","asymmetric nanoparticles","inorganic ligands","heterostructures","catalyst assisted growth","nanocomposites","thermoelectrics"],"day":"25","volume":13,"type":"journal_article","file":[{"date_updated":"2020-07-14T12:47:33Z","creator":"dernst","file_name":"2019_ACSNano_Ibanez.pdf","date_created":"2019-07-16T14:17:09Z","content_type":"application/pdf","relation":"main_file","access_level":"open_access","file_id":"6644","file_size":8628690}],"publication_status":"published","status":"public","_id":"6566","pmid":1,"abstract":[{"lang":"eng","text":"Methodologies that involve the use of nanoparticles as “artificial atoms” to rationally build materials in a bottom-up fashion are particularly well-suited to control the matter at the nanoscale.

Beyond the synthetic control over crystal domain size, shape, crystal phase, and composition, solution-processed nanocrystals allow exquisite surface engineering. This provides additional means to modulate the nanomaterial characteristics and particularly its electronic transport properties. For instance, inorganic surface ligands can be used to tune the type and concentration of majority carriers or to modify the electronic band structure. Herein, we report the thermoelectric properties of SnTe nanocomposites obtained from the consolidation of surface-engineered SnTe nanocrystals into macroscopic pellets. A CdSe-based ligand is selected to (i) converge the light and heavy bands through partial Cd alloying and (ii) generate CdSe nanoinclusions as a secondary phase within the SnTe matrix, thereby reducing the thermal conductivity. These SnTe-CdSe nanocomposites possess thermoelectric figures of merit of up to 1.3 at 850 K, which is, to the best of our knowledge, the highest thermoelectric figure of merit reported for solution-processed SnTe."}],"_id":"6586","intvolume":"       141","pmid":1,"status":"public"},{"article_number":"107768","department":[{"_id":"MaIb"}],"isi":1,"doi":"10.1016/j.dyepig.2019.107768","publication_identifier":{"issn":["0143-7208"]},"language":[{"iso":"eng"}],"external_id":{"isi":["000484870700099"]},"month":"12","oa_version":"None","scopus_import":"1","date_published":"2019-12-01T00:00:00Z","author":[{"last_name":"Yumusak","full_name":"Yumusak, Cigdem","first_name":"Cigdem"},{"full_name":"Prochazkova, Anna Jancik","last_name":"Prochazkova","first_name":"Anna Jancik"},{"first_name":"Dogukan H","orcid":"0000-0002-1075-8857","last_name":"Apaydin","full_name":"Apaydin, Dogukan H","id":"2FF891BC-F248-11E8-B48F-1D18A9856A87"},{"first_name":"Hathaichanok","last_name":"Seelajaroen","full_name":"Seelajaroen, Hathaichanok"},{"last_name":"Sariciftci","full_name":"Sariciftci, Niyazi Serdar","first_name":"Niyazi Serdar"},{"first_name":"Martin","full_name":"Weiter, Martin","last_name":"Weiter"},{"last_name":"Krajcovic","full_name":"Krajcovic, Jozef","first_name":"Jozef"},{"full_name":"Qin, Yong","last_name":"Qin","first_name":"Yong"},{"full_name":"Zhang, Wei","last_name":"Zhang","first_name":"Wei"},{"full_name":"Zhan, Jixun","last_name":"Zhan","first_name":"Jixun"},{"first_name":"Alexander","last_name":"Kovalenko","full_name":"Kovalenko, Alexander"}],"date_updated":"2023-08-29T07:11:09Z","title":"Indigoidine - Biosynthesized organic semiconductor","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","year":"2019","date_created":"2019-08-18T22:00:39Z","article_type":"original","quality_controlled":"1","citation":{"ieee":"C.

We also demonstrate that the same strategy can be used to produce orthorhombic SnSe nanostructures and nanomaterials. NPLs are grown through a screw dislocation-driven mechanism. This mechanism typically results in pyramidal structures, but we demonstrate here that the growth from multiple dislocations results in flower-like structures. Crystallographically textured SnSe2 bulk nanomaterials obtained from the hot pressing of these SnSe2 structures display highly anisotropic charge and heat transport properties and thermoelectric (TE) figures of merit limited by relatively low electrical conductivities. To improve this parameter, SnSe2 NPLs are blended here with metal nanoparticles. The electrical conductivities of the blends are significantly improved with respect to bare SnSe2 NPLs, what translates into a three-fold increase of the TE Figure of merit, reaching unprecedented ZT values up to 0.65."}],"status":"public","main_file_link":[{"open_access":"1","url":"https://upcommons.upc.edu/bitstream/2117/130444/1/Zhang%20preprint.pdf"}],"publication_status":"published"}]
