· Ga1.65Cu0.35S2.65

Ga₁.₆₅Cu₀.₃₅S₂.₆₅ is a quaternary chalcogenide semiconductor compound combining gallium, copper, and sulfur in a mixed-valence structure. This material belongs to the family of I-III-VI₂ semiconductors and is primarily studied as a research compound for photovoltaic and optoelectronic applications, where its tunable bandgap and potential for high absorption coefficients make it a candidate for thin-film solar cells and light-emitting devices. Its copper-gallium sulfide composition offers advantages over traditional binary semiconductors in cost and abundance, though practical device implementation remains largely in the development phase.

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.
