semiconductor· Bi1.98Sb0.02Te3
Bi₁.₉₈Sb₀.₀₂Te₃ is a doped bismuth telluride compound, a narrow-bandgap semiconductor belonging to the V-VI chalcogenide family that forms the basis of commercial thermoelectric materials. This composition represents a heavily bismuth-rich variant with minimal antimony doping, engineered to optimize charge carrier concentration and thermal transport properties for thermoelectric energy conversion. The material is used in applications requiring direct thermal-to-electrical energy conversion or solid-state cooling, where it competes with other bismuth telluride alloys and skutterudites on the basis of doping level, figure-of-merit, and operating temperature range.

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.
