CdCu2GeS4
semiconductor· 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.

Export Control
RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
