International audienceThermoelectric nanowires have been predicted to have superior properties compared to their bulk counterparts due to quantum confinement. We present the synthesis of chalcogenide nanowires A2B3 (A¼Bi, Sb; B¼S, Se, Te) and PbB (B¼S, Se, Te) by electrochemical deposition into highly ordered porous Al2O3 membranes. The narrow pore size distribution of the templates reproducibly yields very homogeneous nanowires upon electrodeposition into the pores. The thermoelectric nanowires presented here were deposited from nonaqueous electrolytes based on Bi3þ and S (and their heavier counterparts). The transmission electron microscopy investigations on released nanowires show the homogeneous growth behavior of the material.Wewill present data on the Seebeck coefficients of nanowire ensembles of various IV-VI and V-VI materials embedded in the porous template
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
