Tl0.07Te1Pb0.93

Tl₀.₀₇Te₁Pb₀.₉₃ is a telluride-based semiconductor alloy combining lead telluride with thallium doping, belonging to the IV–VI narrow-bandgap semiconductor family. This is a research-stage material of interest for thermoelectric applications where the thallium doping modifies electronic and thermal transport properties relative to pure lead telluride. The alloy is notable in solid-state physics for band structure engineering and phonon scattering optimization; it represents compositional tuning strategies used to improve figure-of-merit (ZT) in thermoelectric devices operating at intermediate temperatures.
