· Pb0.95Ge0.05Te

Pb0.95Ge0.05Te is a lead telluride (PbTe)-based semiconductor alloy with 5% germanium substitution on the lead site, belonging to the IV-VI narrow bandgap semiconductor family. This material is primarily investigated for thermoelectric applications where the bandgap engineering and lattice distortion from Ge doping are used to enhance the figure of merit (ZT) and optimize performance around intermediate operating temperatures. The Ge alloying strategy reduces lattice thermal conductivity while tuning the electronic band structure, making it a candidate for solid-state heat-to-electricity conversion and cooling systems.

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.
