· CdCu2GeS4

CdCu₂GeS₄ is a quaternary chalcogenide semiconductor compound combining cadmium, copper, germanium, and sulfur into a tetragonal crystal structure. This material is primarily a research compound of interest for photovoltaic and optoelectronic applications, where its direct bandgap and favorable optical absorption characteristics make it a candidate for thin-film solar cells and light-emitting devices as an alternative to more established II-VI and I-III-VI₂ semiconductors.
