Abstract

An approach based on a solution-based synthesis that produces a thermally stable Ag/oxide/Sb2Te3-Te metal-semiconductor heterostructure is described. With this approach, a figure of merit of zT = 1.0 at 460 K is achieved, a record for a heterostructured material made using wet chemistry. Combining experiments and theory shows that the large increase in the material's Seebeck coefficient results from hot carrier filtering. © 2014 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
