semiconductor· Pb0.97Sn0.03Te
Pb0.97Sn0.03Te is a lead telluride alloy with a small tin dopant, belonging to the narrow-bandgap semiconductor family commonly used in infrared detection and thermoelectric applications. This material is primarily researched and deployed in thermal imaging systems, infrared sensors, and thermoelectric generators operating in the mid-to-long wavelength infrared spectrum, where its bandgap and carrier properties provide sensitivity advantages over wider-bandgap alternatives. The tin addition modifies the electronic structure relative to pure PbTe, making it valuable for tuning detector response and improving performance in cryogenic or moderate-temperature regimes.
