PbTe0.01Se0.99 is a lead telluride–selenide solid solution semiconductor, a narrow-bandgap material engineered for thermoelectric applications where the selenium substitution modifies the electronic structure and thermal properties relative to pure PbTe. This composition falls within the lead chalcogenide family, which dominates mid-temperature thermoelectric power generation and cooling; the specific Se-rich variant is optimized for tuning carrier concentration and lattice thermal conductivity to enhance thermoelectric figure-of-merit in the 400–600 K temperature range.
