· PbTe0.5Se0.5

PbTe₀.₅Se₀.₅ is a lead telluride-selenide solid solution semiconductor belonging to the IV-VI narrow-bandgap family, engineered to optimize thermoelectric performance through compositional tuning of the Te:Se ratio. This material is primarily investigated for mid-temperature thermoelectric power generation and cooling applications, where its bandgap and carrier properties make it competitive with commercial PbTe for converting waste heat to electricity or providing solid-state thermal management in the 300–600 K range. The alloyed composition offers an alternative strategy to PbTe doping for improving figure-of-merit and reducing lattice thermal conductivity through phonon scattering at the Te/Se interfaces.

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.
