· ZnIn2Se4

ZnIn2Se4 is a ternary II-III-VI semiconductor compound combining zinc, indium, and selenium in a crystalline structure. This material belongs to the chalcogenide semiconductor family and is primarily investigated for optoelectronic and photovoltaic applications, where its direct bandgap and tunable electronic properties make it a candidate for light emission, detection, and energy conversion devices. While not yet widely commercialized, ZnIn2Se4 represents a research-stage compound with potential to address niche applications where conventional binary semiconductors (like ZnSe or InSe) fall short in terms of bandgap engineering or defect tolerance.
