semiconductor· Bi1.6Sb0.4Te3
Bi₁.₆Sb₀.₄Te₃ is a bismuth-antimony-telluride compound belonging to the chalcogenide semiconductor family, engineered as a doped variant of the prototypical thermoelectric material Bi₂Te₃. This specific composition is optimized to enhance thermoelectric performance through carrier concentration tuning, making it particularly effective for solid-state heat conversion across moderate temperature ranges. The material is widely deployed in industrial thermoelectric devices and remains a benchmark compound in thermoelectric research due to its favorable balance of electrical conductivity, thermal conductivity, and Seebeck coefficient near room temperature.
