STRUCTURAL INVESTIGATIONS IN THERMOELECTRIC MATERIALS.
Abstract
E SYSTEM XCuSbSe2.(1-x)Cu3SbSe4 has been studied over its complete range. Within the internal x is less than or equal to 0.4, the chalcopyrite structure of Cu3SbSe4 is dominant, and marginal thermoelectric properties are ex hibited. The composition Cu3SbSe3 was found to behave like a single phase, it is weakly p-type with resistivity similar to that of CuSbSe2, but with very low thermal conductivity. The alloy Cu3SbSe3.Cu3SbSe4 assumes the lattice of Cu3SbSe4. The corresponding composition Cu3BiSe3 does not give evidence for the presence of any known selenide of copper or bismuth. It is weakly p-type and shows low resistivity and thermal con ductivity. The n-type System NAg2Se.SnSe2 has been examined. Evidence points to a compound phase Ag8SnSe6. (Author)
