· JVASP-111371· Fe4Te3S

Fe4Te3S is an iron-based ternary compound containing tellurium and sulfur, belonging to the class of metal chalcogenides. This material is primarily of research interest rather than established in mainstream engineering applications, studied for its potential in thermoelectric energy conversion and electronic device applications due to the combination of metallic iron with semiconducting chalcogen elements.
