摘要
Our exploratory research to identify new promising candidates for next generation thermoelectric applications has produced several interesting new materials which are briefly described here. We present their compositions, solid state structures, properties and charge transport behavior. The compounds CsBi4Te6, beta-K2Bi8Se13, Ba4Bi6Se13, Eu2Pb2Bi6Se13, KBi6.33S10,(,) Eu2Pb2Bi4Se10, Ba2Pb2Bi6Se13 and K1.25Pb3.5Bi7.25Se15 are particularly noteworthy.
