· Ga1.8Cu0.2Se2.8

Ga₁.₈Cu₀.₂Se₂.₈ is a quaternary semiconductor compound in the chalcogenide family, combining gallium, copper, and selenium in a non-stoichiometric composition. This is a research-stage material being investigated for photovoltaic and optoelectronic applications, where copper doping of gallium selenide systems aims to engineer bandgap, carrier concentration, and light absorption properties for improved device performance. The material represents an exploratory approach to tailoring semiconductors for thin-film solar cells, photodetectors, and possibly thermoelectric devices where conventional binary or ternary compounds show limitations.

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.
