Bi₂Te₃ Crystals

Bi₂Te₃ Crystals

Bi₂Te₃ (Bismuth Telluride) is a layered thermoelectric material with a rhombohedral crystal structure. It exhibits thermoelectric properties due to its Seebeck coefficient, low thermal conductivity, and anisotropic transport behavior. These characteristics support the use of Bi₂Te₃ in thermoelectric power generation, cooling devices, nanoelectronics, and 2D materials research. Bi₂Te₃ crystals are synthesized using the Chemical Vapor Transport (CVT) method.
