Abstract

Results on the synthesis and characterization of the solid solutions CsBi4-xSbxTe6, CsBi4Te6-ySey, as well as doping experiments on CsBi4Te6 are reported. We report X-ray structural investigations showing that the Sb or Se atoms in these compounds are not uniformly distributed in the lattice but show preferential occupation of specific crystallographic sites. Thermoelectric properties of selected systems are presented.
