Bismuth Tellurium Selenide Description:
Bismuth Tellurium Selenide is a semiconductor alloy, Bi2Te3-xSex, with outstanding thermoelectric properties that enable the efficient conversion of heat into electrical energy. In this material, the elements bismuth, tellurium, and selenium combine, providing better thermoelectric performance compared to pure bismuth telluride. This combination brings about extremely high Seebeck coefficient, good electrical conductivity, and low thermal conductivity, making this material perfectly suitable for effective thermoelectric energy conversion. It could be used in a lot of applications, from waste-heat power generation to solid-state cooling devices, given its stability and efficiency. This turns the material into one of the critical components of progress in thermoelectric technologies due to its satisfactory workability at room and moderate temperatures.
