Bi0.2Sb1.8Te3
semiconductor· Bi0.2Sb1.8Te3
Bi0.2Sb1.8Te3 is a bismuth-antimony telluride compound belonging to the thermoelectric material family, engineered with a specific Bi/Sb ratio to optimize phonon scattering and carrier transport. This alloy composition is widely used in solid-state thermoelectric cooling and power generation devices, particularly where compact thermal management or direct thermal-to-electrical energy conversion is needed without moving parts; it represents a mature alternative to pure Sb2Te3 with improved performance characteristics for mid-range temperature applications.
