· As2Te3

As₂Te₃ is a layered chalcogenide semiconductor compound composed of arsenic and tellurium, belonging to the V-VI semiconductor family. It is primarily investigated in research and emerging applications rather than established industrial production, valued for its narrow bandgap, strong light absorption, and thermoelectric properties. The material shows promise in infrared optoelectronics, phase-change memory devices, and thermoelectric generators, where its anisotropic crystal structure and sensitivity to thermal and optical stimuli offer advantages over conventional semiconductors in specialized niches.

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.
