CAS1304-82-1 Bi2Te3 Bismuth Telluride Powder used for power generation

Brief Description of   Bismuth Telluride Powder​


Bismuth telluride (Bi2Te3) is a gray powder that is a compound of bismuth and tellurium lso known as bismuth(III) telluride.


It is a semiconductor, which, when alloyed with antimony or selenium, is an efficient thermoelectric material for refrigeration or portable power generation.


Bi2Te3 is a topological insulator, and thus exhibits thickness-dependent physical properties.



Properties of  Bismuth Telluride Powder​


Bismuth telluride is a narrow-gap  layered semiconductor with a trigonal unit cell.


The valence and conduction band structure can be described as a many-ellipsoidal model with 6 constant-energy ellipsoids that are centered on the reflection planes.


Bi2Te3 cleaves easily along the trigonal axis due to Van der Waals bonding between neighboring tellurium atoms.


Due to this, bismuth-telluride-based materials used for power generation or cooling applications must be polycrystalline.



Application of Bismuth Telluride Powder​

1. Used in making thermoelectric power generation materials, Semiconductor cooling device materials, etc.
