· Tl0.005Te1Pb0.995

Tl0.005Te1Pb0.995 is a telluride-based semiconductor alloy—specifically a lead telluride (PbTe) compound with a small thallium dopant addition—belonging to the narrow-bandgap IV-VI semiconductor family. This is a research-phase material studied primarily for thermoelectric applications, where the thallium doping is intended to modify carrier concentration and phonon scattering behavior to improve energy conversion efficiency. Historically, PbTe and its doped variants have been used in infrared detectors and thermoelectric generators for specialized aerospace and military systems; the thallium modification represents an experimental attempt to enhance performance over baseline PbTe in waste-heat recovery or temperature-sensing roles.

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.
