· Bi1Te3Sb1

Bi₁Te₃Sb₁ is a quaternary thermoelectric compound based on the bismuth telluride system, where antimony partially substitutes into the bismuth-telluride lattice to modify electronic and thermal transport properties. This material belongs to the family of bismuth chalcogenide thermoelectrics, which are among the most commercially mature thermoelectric materials available, and is investigated primarily for enhanced figure-of-merit (ZT) through carrier concentration tuning and phonon scattering optimization. Industrial applications center on solid-state cooling and power generation where temperature differentials exist; this composition is notable because controlled substitution of antimony can improve performance in specific temperature windows compared to binary Bi₂Te₃, making it relevant to researchers optimizing thermoelectric devices for waste heat recovery, refrigeration, and sensor applications.
