· In2Se3

Indium selenide (In₂Se₃) is a III-VI semiconductor compound with a layered crystal structure, belonging to the family of transition metal chalcogenides. It is primarily of research and emerging technology interest rather than established industrial production, with potential applications in next-generation optoelectronic and energy conversion devices that exploit its direct bandgap and tunable electronic properties.
