semiconductor· In1.3Cu0.7Se2.3
In₁.₃Cu₀.₇Se₂.₃ is a quaternary semiconductor compound combining indium, copper, and selenium in a layered chalcogenide structure. This material belongs to the family of copper-indium selenide semiconductors, which are primarily of research interest for photovoltaic and thermoelectric applications rather than established commercial production. The copper-indium-selenium system is valued for its tunable bandgap and potential in thin-film solar cells and next-generation energy conversion devices, though this particular stoichiometry represents an experimental composition rather than a widely standardized 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.
