Bi2Te3Bismuth telluride crystal substrate is highly oriented crystal ( not single crystal ), which is a narrow gap layered semiconductor with a hexagonal structure. 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. General thermoelectric materials, thermoelectric factor is currently the largest pure-phase block; mechanical dissociation can get high-quality topological insulator material. Specifications:
