semiconductors bismuth telluride rods n type and p type bismuth telluride ingot
Product Description
1.Product Description
Characteristics: | Bismuth telluride is a compound of tellurium and bismuth. It is a narrow gap layered semiconductor with a trigonal unit cell. It mainly occurs in a rare mineral tellurobismuthite. It's produced by sealing bismuth and tellurium metals in a quartz tube under vacuum. When alloyed with selenium or antimony, it acts as an efficient thermoelectric material suitable for portable power generation or refrigeration. |
Production Processes: | Vacuum melting - crystallization (crystal orientation growth) - regional melting - removal of both ends; |
Applications: | Forming P/N section for semiconductor refrigeration, thermoelectric power generation, etc. |
