· Ga1.6Cu0.4S2.6

Ga₁.₆Cu₀.₄S₂.₆ is a quaternary semiconductor compound combining gallium, copper, and sulfur in a non-stoichiometric composition, belonging to the family of I-III-VI₂ chalcogenides. This material is primarily of research interest for photovoltaic and optoelectronic applications, where mixed-cation sulfide semiconductors are being explored as earth-abundant alternatives to conventional cadmium- or lead-based absorbers. The copper-gallium-sulfide system offers tunable bandgaps and potential cost advantages, though it remains largely in the development phase compared to mature semiconductor technologies.

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.
