FeCu2GeS4
metal· JVASP-92261· FeCu2GeS4
FeCu2GeS4 is a quaternary sulfide compound combining iron, copper, and germanium—a material class of significant interest for semiconductor and photovoltaic research rather than conventional structural or metallic applications. This compound belongs to the family of multinary chalcogenides, which are being investigated for next-generation photovoltaic absorbers, thermoelectric devices, and optoelectronic applications due to their tunable bandgap and earth-abundant elemental composition. The material represents an experimental composition aimed at developing cost-effective alternatives to conventional semiconductors and high-efficiency solar cell materials.
