· Sb2 Te4 Pb1

Sb₂Te₄Pb₁ is a lead-doped antimony telluride compound belonging to the chalcogenide semiconductor family, typically investigated as a thermoelectric material. This composition represents a doping variant of the antimony telluride (Sb₂Te₃) system, where lead substitution is used to modify electronic and thermal transport properties for improved thermoelectric performance. While primarily a research material, compounds in this family are of significant interest for solid-state cooling and waste heat recovery applications where traditional mechanical systems are impractical.
