Bi₂Te₃ Crystals

Bi₂Te₃ Crystals

Bi₂Te₃ (Bismuth Telluride) is a well-known layered thermoelectric material with a rhombohedral crystal structure. It exhibits excellent thermoelectric properties due to its high Seebeck coefficient, low thermal conductivity, and strong anisotropic transport behavior. These characteristics make Bi₂Te₃ a key material for applications in thermoelectric power generation, cooling devices, nanoelectronics, and 2D materials research. Our Bi₂Te₃ crystals are synthesized using the Chemical Vapor Transport (CVT) method, ensuring high purity, well-controlled stoichiometry, and good crystallinity.
