· CuZn2InSe4

CuZn2InSe4 is a quaternary semiconductor compound combining copper, zinc, indium, and selenium—a member of the I-III-VI2 semiconductor family related to chalcopyrite structures. This material is primarily of research and development interest for photovoltaic and optoelectronic applications, where it offers potential advantages in bandgap tunability and earth-abundant element composition compared to traditional cadmium-based or gallium arsenide semiconductors.
