· Cu1 Ga1 I4

CuGaI₄ is a quaternary semiconductor compound combining copper, gallium, and iodine in a 1:1:4 stoichiometry. This material belongs to the family of halide perovskites and related semiconductor structures, which are primarily under investigation for optoelectronic and photovoltaic applications due to their tunable bandgap and light-absorption properties. While not yet established in high-volume industrial production, CuGaI₄ and similar copper halide semiconductors are of research interest for next-generation solar cells, radiation detectors, and LED applications where cost-effective alternatives to conventional semiconductors like GaAs or CdTe are sought.

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.
