· Pb0.85Se0.85Ge0.15Te0.15

Pb0.85Se0.85Ge0.15Te0.15 is a quaternary lead chalcogenide semiconductor alloy combining lead selenide and lead telluride with germanium doping, belonging to the IV-VI narrow-bandgap semiconductor family. This material composition is primarily investigated for thermoelectric applications where its tuned bandgap and carrier concentration enable efficient solid-state heat-to-electricity conversion, with particular relevance to mid-temperature radioisotope thermoelectric generators and waste heat recovery systems where its stability and performance exceed binary lead telluride alternatives.

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.
