· In2 Se3

In₂Se₃ is a III-VI layered semiconductor compound composed of indium and selenium, belonging to the family of van der Waals materials with a naturally layered crystal structure. It is primarily investigated in research and emerging device applications for its tunable band gap, strong light-matter interactions, and potential for integration into flexible and transparent electronics. The material is notably under development for next-generation photovoltaic devices, photodetectors, and field-effect transistors where its layered structure enables both high performance and mechanical flexibility compared to conventional bulk semiconductors.
