CsInSn2Se6

CsInSn₂Se₆ is a ternary selenide semiconductor compound combining cesium, indium, and tin in a layered crystal structure, belonging to the family of metal chalcogenides studied for optoelectronic applications. This is primarily a research-stage material rather than a commercially established engineering material; it is investigated for potential use in infrared detection, photovoltaics, and nonlinear optical devices where the wide bandgap and layered structure may offer advantages over conventional semiconductors. The compound represents an emerging class of hybrid halide and chalcogenide perovskites, where substituting different metal cations allows tuning of electronic and optical properties for next-generation photodetectors and energy conversion devices.
