semiconductor· 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.

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
