ZnCu2GeS4
semiconductor· ZnCu2GeS4
ZnCu2GeS4 is a quaternary semiconducting compound belonging to the diamond-like semiconductor family, combining zinc, copper, germanium, and sulfur in a tetrahedral crystal structure. This material is primarily of research interest for optoelectronic and photovoltaic applications, where its tunable bandgap and non-linear optical properties make it a candidate for infrared detectors, frequency conversion devices, and thin-film solar cells. While not yet widely deployed industrially, compounds in this family are investigated as alternatives to conventional semiconductors due to their potential for improved absorption coefficients and environmental advantages over lead-based or cadmium-based semiconductors.
