semiconductor· Ge0.3Te1Pb0.7
Ge₀.₃Te₁Pb₀.₇ is a lead-tellurium-germanium chalcogenide compound belonging to the narrow-bandgap semiconductor family, typically investigated as a thermoelectric and infrared-optoelectronic material. This composition sits within the PbTe–GeTe pseudobinary system, a well-studied platform for tuning band structure and carrier transport in lead chalcogenides. The material is primarily of research and developmental interest for mid-infrared sensing, thermoelectric power generation in waste-heat recovery, and potentially phase-change memory applications, where its mixed composition offers opportunities to engineer thermal, electrical, and optical properties relative to binary PbTe or GeTe.
