Bismuth telluride

Description:
Bismuth telluride (Bi2Te3) is a compound composed of bismuth and tellurium, notable for its semiconducting properties, particularly in thermoelectric applications. It typically appears as a gray or black crystalline solid and exhibits a layered structure, which contributes to its unique electronic and thermal characteristics. Bismuth telluride is widely used in thermoelectric devices for power generation and refrigeration, operating efficiently near room temperature. Its thermoelectric performance is characterized by a high Seebeck coefficient, low thermal conductivity, and good electrical conductivity, making it an ideal material for converting temperature differences into electrical voltage. Additionally, bismuth telluride can be doped with various elements to enhance its thermoelectric efficiency. It is relatively stable under ambient conditions but can degrade at elevated temperatures. Safety considerations include handling it with care, as it can release toxic fumes upon decomposition. Overall, bismuth telluride is a critical material in the field of thermoelectrics and continues to be the subject of extensive research for improving its performance and applications.
