· Cu0.05Ga1.95S2.95

Cu0.05Ga1.95S2.95 is a copper-doped gallium sulfide semiconductor compound, representing a variation of the GaS family with controlled copper substitution for band structure engineering. This material is primarily of research interest for optoelectronic and photovoltaic applications, where the copper doping modifies electronic properties to enhance light absorption and carrier transport compared to undoped gallium sulfide. The compound belongs to the wider family of chalcogenide semiconductors investigated for thin-film solar cells, photodetectors, and nonlinear optical devices where tunable bandgap and improved efficiency are design goals.
