· Ga1.5Cu0.5S2.5

Ga1.5Cu0.5S2.5 is a mixed-metal sulfide semiconductor compound combining gallium and copper in a non-stoichiometric ratio. This is a research-phase material within the family of I-III-VI semiconductors; compounds in this class are investigated for optoelectronic and photovoltaic applications due to their tunable band gaps and potential for absorber layers in thin-film solar cells. The specific composition represents an exploratory attempt to engineer defect states and carrier transport properties by deliberate copper doping of gallium sulfide.

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.
