The standard computational framework combines density functional theory (DFT) with nonequilibrium Green’s functions (NEGF) using low-rung exchange-correlation functionals such as PBE, which overestimate the conductances. More advanced correction methods exist but require complex workflows and high computational cost, limiting their accessibility. Here, we introduce a physically motivated approach that approximates results obtained with high-rung functionals. Our method fits the PBE-calculated transmission to a Breit-Wigner form and subsequently refines the fit parameters using molecular orbital energies and metal densities of states computed for the isolated subsystems with high-rung functionals. This approach is applicable to a broad range of molecular junctions yielding conductance values in quantitative agreement with experiments. Our approach is simple, low-cost, and accurate, making it well-suited for routine and large-scale prediction of single-molecule junction conductance."}],"language":[{"iso":"eng"}],"tmp":{"image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"has_accepted_license":"1","status":"public","external_id":{"chemrxivid":["10.26434/chemrxiv.15001696"],"pmid":["42223342"]},"oa_version":"Published Version","day":"01","citation":{"apa":"Gulyaev, A., Hazarika, J., Liu, Z.-F., &#38; Venkataraman, L.

This trade-off is particularly pronounced in polymer scintillators, which, despite their fast emission, exhibit low density and low atomic numbers, limiting the radiation attenuation factor, resulting in low detection efficiency. Here, we overcome this limitation by creating a heterostructure scintillator of alternating nanometric layers, combining fast light-emitting polymer scintillator layers and transparent stopping layers with a high radiation attenuation factor. The nanolayer thicknesses are tuned to optimize the penetration depth of recoil electrons in active emissive layers, maximizing the conversion of X-rays to visible light. This design increases light output by up to 1.5 times and enhances imaging resolution by a factor of 2 compared to homogeneous polymer scintillators due to the ability to use thinner samples. These results demonstrate the potential of heterostructure scintillators as next-generation detector materials, overcoming the limitations of homogeneous scintillators."}],"doi":"10.1021/acs.nanolett.4c05353","publication_identifier":{"issn":["1530-6984"],"eissn":["1530-6992"]},"status":"public","tmp":{"image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"issue":"9","citation":{"ista":"Be’er O, Shultzman A, Strassberg R, Dosovitskiy G, Veber N, Schuetz R, Roques-Carmes C, Kaminer I, Bekenstein Y. 2025.

Although radially and linearly conjugated molecules have been studied previously in isolation as junction-bridging molecular electronic units, this is the first study to examine molecules where both topologies are operative. Our results reveal that the presence of radial CPP components within the junction-spanning pathway leads to a reduction in the conductance of the backbone compared to model linear phenyl substituents. Through tight-binding and DFT-based calculations, we attribute this conductance change to intramolecular van der Waals (vdW) interactions between the CPP ring and the junction-spanning arylene-ethynylene molecular backbone.

Unlike ferrocene, both ruthenocene and osmocene can form molecular junctions under ambient conditions without chemical linkers. We propose that Au electrodes bind to the metal center and one of the cyclopentadienyl (Cp) rings via a ring-slippage process, forming a molecular junction. Control measurements demonstrate that the metal centers bind to uncoordinated Au exclusively in the +3 oxidation state.

By varying these linkers, we systematically modulate the frontier molecular orbital energies and fine-tune transport behavior. Our experimental results are supported by DFT-based calculations, which feature a new computationally efficient correction to standard PBE-level transmission predictions.

However, the nature of the gold–thiolate bond as it relates to the solvent has seldom been investigated. It is known that solvents can impact the electronic structure of single-molecule junctions, but the correlation between the solvent and dithiol-linked single-molecule junction conductance is not well understood. We study molecular junctions formed with thiol-terminated phenylenes from both 1-chloronaphthalene and 1-bromonaphthalene solutions. We find that the most probable conductance and the distribution of conductances are both affected by the solvent. First-principles calculations show that junction conductance depends on the binding configurations (adatom, atop, and bridge) of the thiolate on the Au surface, as has been shown previously. More importantly, we find that brominated solvents can restrict the binding of thiols to specific Au sites. This mechanism offers new insight into the effects of the solvent environment on covalent bonding in molecular junctions."}],"language":[{"iso":"eng"}],"publication_identifier":{"eissn":["1530-6992"],"issn":["1530-6984"]},"doi":"10.1021/acs.nanolett.3c04058","status":"public","citation":{"ista":"Dalmieda J, Shi W, Li L, Venkataraman L. 2024.

Most studies have focused on spherical objects, whereas biologically relevant shapes can be highly anisotropic. In this letter, we use an experimental model system based on Giant Unilamellar Vesicles (GUVs) and dumbbell-shaped colloidal particles to mimic and investigate the first stage of the passive endocytic process: engulfment of an anisotropic object by the membrane. Our model has specific ligand–receptor interactions realized by mobile receptors on the vesicles and immobile ligands on the particles. Through a series of experiments, theory, and molecular dynamics simulations, we quantify the wrapping process of anisotropic dumbbells by GUVs and identify distinct stages of the wrapping pathway. We find that the strong curvature variation in the neck of the dumbbell as well as membrane tension are crucial in determining both the speed of wrapping and the final states."}],"isi":1,"language":[{"iso":"eng"}],"publication_identifier":{"issn":["1530-6984"],"eissn":["1530-6992"]},"doi":"10.1021/acs.nanolett.3c00375","ddc":["540"],"volume":23,"intvolume":"        23","acknowledgement":"We sincerely thank Casper van der Wel for providing open-source packages for tracking, as well as Yogesh Shelke for his assistance with PAA coverslip preparation and Rachel Doherty for her assistance with particle functionalization.

Typically, metal–molecule–metal junctions are measured using a break-junction method where electrode separation is mechanically evolving during measurement. Here, to probe the impact of the junction geometry on conductance, we apply a sinusoidal modulation to the molecular junction electrode position. Simultaneously, we probe the nonlinearity of the current–voltage characteristics of each junction through a modulation in the applied bias at a different frequency. In turn, we show that junctions formed with molecules that have different molecule–electrode interfaces exhibit statistically distinguishable Fourier-transformed conductances. In particular, we find a marked bias dependence for the modulation of junctions where transmission is mediated thorough the van der Waals (vdW) interaction.

For instance, upon applying a perpendicular electric field, its band structure exhibits several off-center Dirac points (so-called Dirac gullies) in each valley. Here, the formation of Dirac gullies and the interaction-induced breakdown of gully coherence is explored via magnetotransport measurements in high-quality Bernal-stacked (ABA) trilayer graphene. At zero magnetic field, multiple Lifshitz transitions indicating the formation of Dirac gullies are identified. In the quantum Hall regime, the emergence of Dirac gullies is evident as an increase in Landau level degeneracy. When tuning both electric and magnetic fields, electron–electron interactions can be controllably enhanced until, beyond critical electric and magnetic fields, the gully degeneracy is eventually lifted. The arising correlated ground state is consistent with a previously predicted nematic phase that spontaneously breaks the rotational gully symmetry."}],"isi":1,"doi":"10.1021/acs.nanolett.2c00435","publication_identifier":{"eissn":["1530-6992"],"issn":["1530-6984"]},"status":"public","issue":"8","citation":{"apa":"Winterer, F., Seiler, A.

Although several experimental studies have shown counter examples, robust models to describe this temperature dependence have not been thoroughly developed. Here, we demonstrate that dynamic molecular structures lead to temperature-dependent conductance within coherent tunneling regime. Using a custom-built variable-temperature scanning tunneling microscopy break-junction instrument, we find that oligo[n]phenylenes exhibit clear temperature-dependent conductance. Our calculations reveal that thermally activated dihedral rotations allow these molecular wires to have a higher probability of being in a planar conformation. As the tunneling occurs primarily through π-orbitals, enhanced coplanarization substantially increases the time-averaged tunneling probability. These calculations are consistent with the observation that more rotational pivot points in longer molecular wires leads to larger temperature-dependence on conductance. These findings reveal that molecular conductance within coherent and off-resonant electron transport regimes can be controlled by manipulating dynamic molecular structure.","lang":"eng"}],"language":[{"iso":"eng"}],"intvolume":"        22","fulldoi":"https://doi.org/10.1021/acs.nanolett.2c01549","volume":22,"external_id":{"pmid":["35640062"]},"oa_version":"None","day":"31","citation":{"ista":"Lee W, Louie S, Evans AM, Orchanian NM, Stone IB, Zhang B, Wei Y, Roy X, Nuckolls C, Venkataraman L. 2022.

Here, we demonstrate that a similar concept can be extended to the optics realm, particularly to propagating phonon polaritons–hybrid light-matter interactions. To do this, we fabricate stacks composed of two twisted slabs of a vdW crystal (α-MoO3) supporting anisotropic phonon polaritons (PhPs), and image the propagation of the latter when launched by localized sources. Our images reveal that, under a critical angle, the PhPs isofrequency curve undergoes a topological transition, in which the propagation of PhPs is strongly guided (canalization regime) along predetermined directions without geometric spreading. These results demonstrate a new degree of freedom (twist angle) for controlling the propagation of polaritons at the nanoscale with potential for nanoimaging, (bio)-sensing, or heat management.","lang":"eng"}],"isi":1,"doi":"10.1021/acs.nanolett.0c01673","publication_identifier":{"issn":["1530-6984"],"eissn":["1530-6992"]},"volume":20,"fulldoi":"https://doi.org/10.1021/acs.nanolett.0c01673","intvolume":"        20","acknowledgement":"J.T.-G. and G.Á.-P. acknowledge support through the Severo Ochoa Program from the\r\nGovernment of the Principality of Asturias (nos.

For many properties the micro- and nanostructure plays a crucial role and one key challenge is control and detection of chemical and physical processes in the confined microstructure and nanopores of the wooden cell wall. In this study, correlative Raman and atomic force microscopy show high potential for tracking in situ molecular rearrangement of wood polymers during compression. More water molecules (interpreted as wider cellulose microfibril distances) and disentangling of hemicellulose chains are detected in the opened cell wall regions, whereas an increase of lignin is revealed in the compressed areas. These results support a new more “loose” cell wall model based on flexible lignin nanodomains and advance our knowledge of the molecular reorganization during deformation of wood for optimized processing and utilization.","lang":"eng"}],"isi":1,"language":[{"iso":"eng"}],"publication_identifier":{"eissn":["1530-6992"]},"doi":"10.1021/acs.nanolett.0c00205","ddc":["530"],"volume":20,"intvolume":"        20","fulldoi":"https://doi.org/10.1021/acs.nanolett.0c00205"},{"external_id":{"pmid":["32479090"],"isi":["000548893200066"]},"oa_version":"Published Version","day":"01","citation":{"apa":"Katsaros, G., Kukucka, J., Vukušić, L., Watzinger, H., Gao, F., Wang, T., … Held, K.

Here, we interrogate the structural changes of a single diketopyrrolopyrrole (DPP) molecule induced by charge transport at a high bias using scanning tunneling microscope break junction (STM-BJ) techniques. Specifically, we demonstrate that application of a high bias increases the average nonresonant conductance of single Au–DPP–Au junctions. We infer from the increased conductance that resonant charge transport induces planarization of the molecular backbone. We further show that this conformational planarization is assisted by thermally activated junction reorganization. The planarization only occurs under specific electronic conditions, which we rationalize by ab initio calculations. These results emphasize the need for a comprehensive view of single-molecule junctions which includes both the electronic properties and structure of the molecules and the electrodes when designing electrically driven single-molecule motors.","lang":"eng"}],"language":[{"iso":"eng"}],"publication_identifier":{"eissn":["1530-6992"],"issn":["1530-6984"]},"doi":"10.1021/acs.nanolett.0c04260","volume":21,"intvolume":"        21","fulldoi":"https://doi.org/10.1021/acs.nanolett.0c04260","quality_controlled":"1","publisher":"American Chemical Society","publication_status":"published","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","page":"673-679","scopus_import":"1","year":"2020","type":"journal_article","OA_type":"closed access","extern":"1","pmid":1,"_id":"17902","author":[{"full_name":"Zang, Yaping","first_name":"Yaping","last_name":"Zang"},{"full_name":"Fung, E-Dean","first_name":"E-Dean","last_name":"Fung"},{"full_name":"Fu, Tianren","first_name":"Tianren","last_name":"Fu"},{"last_name":"Ray","first_name":"Suman","full_name":"Ray, Suman"},{"first_name":"Marc H.","last_name":"Garner","full_name":"Garner, Marc H."},{"first_name":"Anders","last_name":"Borges","full_name":"Borges, Anders"},{"full_name":"Steigerwald, Michael L.","last_name":"Steigerwald","first_name":"Michael L."},{"last_name":"Patil","first_name":"Satish","full_name":"Patil, Satish"},{"full_name":"Solomon, Gemma","first_name":"Gemma","last_name":"Solomon"},{"full_name":"Venkataraman, Latha","id":"9ebb78a5-cc0d-11ee-8322-fae086a32caf","first_name":"Latha","orcid":"0000-0002-6957-6089","last_name":"Venkataraman"}],"date_published":"2020-12-18T00:00:00Z","publication":"Nano Letters","date_updated":"2024-12-10T10:26:22Z","month":"12","article_processing_charge":"No","title":"Voltage-induced single-molecule junction planarization","article_type":"letter_note","date_created":"2024-09-09T06:48:30Z"},{"quality_controlled":"1","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","page":"8912-8918","publisher":"American Chemical Society","publication_status":"published","OA_type":"closed access","extern":"1","year":"2020","scopus_import":"1","type":"journal_article","pmid":1,"_id":"17903","publication":"Nano Letters","author":[{"full_name":"Fung, E-Dean","first_name":"E-Dean","last_name":"Fung"},{"id":"9ebb78a5-cc0d-11ee-8322-fae086a32caf","full_name":"Venkataraman, Latha","last_name":"Venkataraman","orcid":"0000-0002-6957-6089","first_name":"Latha"}],"date_published":"2020-11-18T00:00:00Z","article_processing_charge":"No","month":"11","date_updated":"2024-12-10T10:28:52Z","date_created":"2024-09-09T07:12:19Z","article_type":"letter_note","title":"Too cool for blackbody radiation: Overbias photon emission in ambient STM due to multielectron processes","issue":"12","citation":{"mla":"Fung, E.

Surprisingly, the photons emitted can have energies exceeding the energy supplied to the electrons by the bias. Three mechanisms for generating these so-called overbias photons have been proposed, but the relationship between these mechanisms has not been clarified. In this work, we argue that multielectron processes provide the best framework for understanding overbias light emission in tunnel junctions. Experimentally, we demonstrate for the first time that the superlinear dependence of emission on conductance predicted by this theory is robust to the temperature of the tunnel junction, indicating that tunnel junctions are a promising candidate for electrically driven broadband photon sources.","lang":"eng"}],"doi":"10.1021/acs.nanolett.0c03994","publication_identifier":{"eissn":["1530-6992"],"issn":["1530-6984"]},"volume":20,"fulldoi":"https://doi.org/10.1021/acs.nanolett.0c03994","intvolume":"        20"},{"pmid":1,"type":"journal_article","year":"2020","scopus_import":"1","extern":"1","OA_type":"closed access","publication_status":"published","publisher":"American Chemical Society","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","page":"8415-8419","quality_controlled":"1","title":"Cumulene wires display increasing conductance with increasing length","article_type":"letter_note","date_created":"2024-09-09T07:16:20Z","month":"10","date_updated":"2024-12-10T10:41:40Z","article_processing_charge":"No","date_published":"2020-10-23T00:00:00Z","author":[{"full_name":"Zang, Yaping","first_name":"Yaping","last_name":"Zang"},{"last_name":"Fu","first_name":"Tianren","full_name":"Fu, Tianren"},{"full_name":"Zou, Qi","first_name":"Qi","last_name":"Zou"},{"full_name":"Ng, Fay","last_name":"Ng","first_name":"Fay"},{"first_name":"Hexing","last_name":"Li","full_name":"Li, Hexing"},{"last_name":"Steigerwald","first_name":"Michael L.","full_name":"Steigerwald, Michael L."},{"first_name":"Colin","last_name":"Nuckolls","full_name":"Nuckolls, Colin"},{"full_name":"Venkataraman, Latha","id":"9ebb78a5-cc0d-11ee-8322-fae086a32caf","first_name":"Latha","last_name":"Venkataraman","orcid":"0000-0002-6957-6089"}],"publication":"Nano Letters","_id":"17906","status":"public","oa_version":"None","external_id":{"pmid":["33095021"]},"day":"23","citation":{"ista":"Zang Y, Fu T, Zou Q, Ng F, Li H, Steigerwald ML, Nuckolls C, Venkataraman L. 2020.

They are likely to be good candidates for molecular-scale conducting wires as they are predicted to have a high-conductance. In this study, we first characterize the single-molecule conductance of a series of cumulenes and polyynes with a backbone ranging in length from 4 to 8 carbon atoms, including [7]cumulene, the longest cumulenic carbon wire studied to date for molecular electronics. We observe different length dependence of conductance when comparing these two forms of carbon wires. Polyynes exhibit conductance decays with increasing molecular length, while cumulenes show a conductance increase with increasing molecular length. Their distinct conducting behaviors are attributed to their different bond length alternation, which is supported by theoretical calculations. This study confirms the long-standing theoretical predictions on sp-hybridized carbon wires and demonstrates that cumulenes can form highly conducting molecular wires.","lang":"eng"}],"language":[{"iso":"eng"}]},{"status":"public","oa_version":"Preprint","external_id":{"pmid":["32787164"]},"day":"03","main_file_link":[{"open_access":"1","url":"https://doi.org/10.26434/chemrxiv.12252059.v1"}],"citation":{"ieee":"M.

Of widespread interest in fundamental studies and real-world applications, they have also attracted some interest as functional elements of molecular-scale devices. Here we investigate the impact of the configurational degrees of freedom of a ferrocene derivative on its single-molecule junction conductance. Measurements indicate that the conductance of the ferrocene derivative, which is suppressed by 2 orders of magnitude as compared to a fully conjugated analogue, can be modulated by altering the junction configuration. Ab initio transport calculations show that the low conductance is a consequence of destructive quantum interference effects of the Fano type that arise from the hybridization of localized metal-based d-orbitals and the delocalized ligand-based π-system. By rotation of the Cp rings, the hybridization, and thus the quantum interference, can be mechanically controlled, resulting in a conductance modulation that is seen experimentally.","lang":"eng"}],"language":[{"iso":"eng"}],"pmid":1,"year":"2020","type":"journal_article","scopus_import":"1","extern":"1","OA_type":"green","publication_status":"published","publisher":"American Chemical Society","page":"6381-6386","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","OA_place":"repository","oa":1,"quality_controlled":"1","title":"Mechanically tunable quantum interference in ferrocene-based single-molecule junctions","article_type":"letter_note","date_created":"2024-09-09T07:18:19Z","month":"08","date_updated":"2024-12-10T10:49:18Z","article_processing_charge":"No","date_published":"2020-08-03T00:00:00Z","author":[{"first_name":"María","last_name":"Camarasa-Gómez","full_name":"Camarasa-Gómez, María"},{"full_name":"Hernangómez-Pérez, Daniel","first_name":"Daniel","last_name":"Hernangómez-Pérez"},{"last_name":"Inkpen","first_name":"Michael S.","full_name":"Inkpen, Michael S."},{"full_name":"Lovat, Giacomo","last_name":"Lovat","first_name":"Giacomo"},{"last_name":"Fung","first_name":"E-Dean","full_name":"Fung, E-Dean"},{"full_name":"Roy, Xavier","first_name":"Xavier","last_name":"Roy"},{"last_name":"Venkataraman","orcid":"0000-0002-6957-6089","first_name":"Latha","id":"9ebb78a5-cc0d-11ee-8322-fae086a32caf","full_name":"Venkataraman, Latha"},{"full_name":"Evers, Ferdinand","first_name":"Ferdinand","last_name":"Evers"}],"publication":"Nano Letters","_id":"17908"}]
