Sb2 Te3

Antimony telluride (Sb₂Te₃) is a narrow-bandgap semiconductor compound belonging to the chalcogenide family, commonly used as the p-type leg in thermoelectric devices. It is a cornerstone material in thermoelectric cooling and power generation applications, particularly valued for its performance near room temperature and its ability to form efficient couples with n-type bismuth telluride (Bi₂Te₃). The material is well-established in commercial thermoelectric modules for electronic cooling, thermal management in optoelectronics, and emerging applications in waste heat recovery, though ongoing research explores topological surface states and phase-change memory variants.
