Abstract

The increased interest in research and development on thermoelectric materials is partly due to the need for improved efficiency in the global utilization of energy resources. Historically, Bi2Te3 occupies an important position in the thermoelectric community. For commercial cooling applications, Bi2Te3 is currently the most practical and efficient material. Compounds in the Bi2Te3-xSx system have also been studied in effort to further improve thermoelectric performance. This paper summarizes our two recent research efforts on the bismuth telluride systems, including the certification of a standard reference material (SRM®) for low temperature Seebeck coefficient using Te-doped Bi2Te3, and the composition/structure/property relationship studies of the effect of S alloying with Te in a Bi2Te3-xSx single crystal.
