Bismuth Tellurium Selenide Description:
Bismuth Tellurium Selenide (Bi2Te3-xSex) is a semiconductor alloy with exceptional thermoelectric properties, characterized by its ability to efficiently convert heat into electrical energy. This material combines the elements bismuth, tellurium, and selenium, which enhances its thermoelectric performance compared to pure bismuth telluride. Bismuth Tellurium Selenide exhibits a high Seebeck coefficient, excellent electrical conductivity, and low thermal conductivity, which are crucial for effective thermoelectric energy conversion. Its stability and efficiency make it suitable for use in a variety of applications, including power generation from waste heat and solid-state cooling devices. The material’s ability to operate effectively at room and moderate temperatures makes it a key component in advancing thermoelectric technologies.
