· Co2 Sb2 S2

Co₂Sb₂S₂ is a ternary chalcogenide semiconductor compound combining cobalt, antimony, and sulfur elements. This material belongs to the family of transition metal chalcogenides, which are primarily of research and developmental interest for next-generation electronic and optoelectronic applications rather than established industrial use. The compound is investigated for potential applications in thermoelectric devices, photovoltaic materials, and solid-state electronics where its semiconducting properties and layered crystal structure could offer advantages in thermal-to-electric energy conversion or light absorption.
