· In2 Cu2 P4 Se12

In₂Cu₂P₄Se₁₂ is a quaternary semiconductor compound combining indium, copper, phosphorus, and selenium elements, belonging to the family of mixed-metal chalcogenides. This material is primarily of research interest for optoelectronic and thermoelectric applications, where its layered structure and tunable bandgap offer potential advantages over single-element semiconductors. While not yet widely deployed in mainstream commercial products, compounds in this family are being investigated for photovoltaic devices, infrared detectors, and solid-state energy conversion due to their ability to engineer electronic properties through compositional variation.
