Bi2Te3 - Bismuth telluride |
Bismuth telluride is a semiconductor material used predominantly for cooling and power generation. To regulate the conductivity of Bi2Te3 and enhance its thermoelectric qualities it is usually doped with antimony or selenium. Other dopants (except gases and radioactive materials) are available upon request. |
