· Te0.05Pb1Se0.95

Te₀.₀₅Pb₁Se₀.₉₅ is a lead selenide-based narrow-bandgap semiconductor alloy with minor tellurium doping, belonging to the IV-VI lead chalcogenide family. This material is primarily investigated in thermoelectric and infrared detection applications, where the tellurium incorporation modifies band structure and charge carrier dynamics relative to pure PbSe. The composition sits between well-studied binary PbSe and PbTe end members, making it a research compound for optimizing thermoelectric efficiency, IR sensor responsivity, and thermal stability in mid-infrared wavelength regimes.

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.
