The Synthesis and Thermoelectric Properties of the n-Type Solid Solution Bi_2-xSb_xTe₃ (x < 1).

ABSTRACT: Commercial Peltier cooling devices and thermoelectric generators mostly use bismuth telluride-based materials, specifically its alloys with Sb₂Te₃ for the p-type legs and its alloys with Bi₂Se₃ for the n-type legs. If the p-type materials perform with zT well above the unity around room temperature, the n-type counterpart is lacking efficiency in this temperature range, and has the disadvantage of containing selenium. Indeed, despite the fact that selenium is not environmentally benign and that its handling requires precautions, the use of selenium does not facilitate the optimization of thermoelectric performance at or around room temperature, as the presence of selenium results in a larger band gap. In this study, we investigate the feasibility
