In3Se

Indium selenide (In₃Se) is a III–VI semiconductor ceramic compound combining indium and selenium. It belongs to the family of layered chalcogenide materials and is primarily of research and developmental interest rather than a mature commercial material. In₃Se and related indium selenides are investigated for optoelectronic and photovoltaic applications where their direct bandgap and layered crystal structure offer potential for thin-film devices, photodetectors, and next-generation solar cells; however, these materials remain largely in the experimental phase with limited industrial deployment compared to established semiconductors like silicon or gallium arsenide.
