· ZnGa2Se4

ZnGa₂Se₄ is a quaternary semiconductor compound belonging to the II-III-VI family of materials, combining zinc and gallium chalcogenides in a defect chalcopyrite structure. It is primarily investigated in research settings for optoelectronic and photovoltaic applications, where its direct bandgap and tunable electronic properties make it a candidate for solar cells, photodetectors, and nonlinear optical devices. While not yet widely deployed in high-volume production, this material class is notable for bridging traditional binary semiconductors (like GaAs or ZnSe) and offering compositional flexibility to optimize performance for specific wavelength ranges and device architectures.
