Product Name: 4n Bi2te3/Bismuth Telluride/Bismuth Telluride Semiconductor Model NO.: 99.99% Carbon Content: Low Carbon Material: Bi2te3 Product Type: Pellet Trademark: Xinrong Transport Package: 1kg/Polyester Bag Specification: 1.4*1.4*1.7mm Origin: China Product Description DescriptionsBismuth telluride is acompound of tellurium and bismuth. It is anarrow gap layered semiconductor with atrigonal unit cell. It mainly occurs in arare mineral tellurobismuthite. It's produced by sealing bismuth and tellurium metals in aquartz tube under vacuum.When alloyed with selenium or antimony, it acts as an efficient thermoelectric material suitable for portable power generation or refrigeration.Specifications1.
