Product Description
thermoelectric TEC TEG p/n bi2te3 n-type p-type bismuth telluride pellet 1. Product Descriptions
Bismuth telluride is a compound of tellurium and bismuth.
When alloyed with selenium or antimony, it acts as an efficient thermoelectric material suitable for portable power generation or refrigeration. It is a narrow gap layered semiconductor with a trigonal unit cell. It mainly occurs in a rare mineral tellurobismuthite.
It is produced by sealing bismuth and tellurium metals in a quartz tube under vacuum.
