· JVASP-2244· Sb2Te2Se

Sb₂Te₂Se is a mixed chalcogenide ceramic compound belonging to the tellurium-selenium family, structurally related to layered van der Waals materials used in thermoelectric and optoelectronic applications. This material is primarily of research and emerging technology interest rather than established industrial production, with potential applications in phase-change memory, thermoelectric energy conversion, and infrared optical devices where its layered structure and thermal properties offer advantages over binary telluride or selenide alternatives.
