It is also shown here how the diversity of valences in the constituent elements allows an effective control of their electrical conductivity through the adjustment of the cation ratios. At the same time, while the crystallographic complexity of quaternary chalcogenides is associated with intrinsically low thermal conductivities, the reduction of the lattice dimensions to the nanoscale further reduces the materials thermal conductivity. In the specific case of the stannite crystal structure, a convenient slab distribution of the valence band maximum states permits a partial decoupling of the p-type electrical conductivity from both the Seebeck coefficient and the thermal conductivity. Combining these features, we demonstrate how an initial optimization of the nanocrystals Cd/Cu ratio allowed us to obtain low-temperature solution-processed materials with ZT values up to 0.71 at 685 K."}],"publist_id":"7489","publisher":"American Chemical Society","extern":"1","article_processing_charge":"No","language":[{"iso":"eng"}],"issue":"3","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","intvolume":"        24","doi":"10.1021/cm2031812","article_type":"original","acknowledgement":"This work was supported by the Spanish MICINN Projects MAT2008-05779, MAT2008-03400-E/MAT, MAT2010-15138, ENE2008-03277-E/CON, CSD2009-00050. and CSD2009-00013.
