· Sb2 Te1 Se2

Sb2Te1Se2 is a ternary chalcogenide semiconductor compound belonging to the V-VI group semiconductors, related to the thermoelectric material family exemplified by bismuth telluride and antimony telluride alloys. This material is primarily investigated for thermoelectric applications where the ability to convert temperature gradients into electrical current (or vice versa) is valuable, and represents an experimental composition within the broader Sb-Te-Se system being explored to optimize thermoelectric figure of merit and thermal stability. The substitution of selenium into antimony telluride compositions is designed to tune band structure and phonon scattering for improved performance in thermal energy harvesting and cooling devices compared to binary parent compounds.

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.
