· PbTe0.99Se0.01

PbTe0.99Se0.01 is a lead telluride–based narrow-bandgap semiconductor alloy with a small selenium substitution, belonging to the IV–VI thermoelectric material family. This composition is engineered for mid-to-high temperature thermoelectric applications where conversion between heat and electrical power is needed; the selenium doping tunes the bandgap and carrier concentration to optimize the figure of merit (ZT) for power generation or solid-state cooling. Compared to unalloyed PbTe, this selenium-doped variant is notable for achieving improved thermoelectric performance in the 500–700 K temperature range, making it relevant for waste-heat recovery from industrial processes and next-generation radioisotope thermoelectric generators (RTGs) in space missions.

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.
