· Pb0.96TeTl0.04

Pb0.96TeTl0.04 is a tellurium-based semiconductor alloy in which a small fraction of lead is replaced by thallium dopant. This material belongs to the IV-VI narrow-bandgap semiconductor family, related to lead telluride (PbTe), a well-established thermoelectric compound. The thallium substitution is employed to modify electronic properties—typically carrier concentration and bandgap—making this a research-grade composition designed to optimize thermoelectric performance or infrared detection sensitivity. Engineers and materials scientists would select this doped variant over undoped PbTe when fine-tuned electrical conductivity, Seebeck coefficient, or optical response is critical for waste-heat recovery systems or mid-wave infrared sensing applications.

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.
