· Cr1 In1 Cu2

Cr₁In₁Cu₂ is a ternary intermetallic semiconductor compound combining chromium, indium, and copper in a 1:1:2 stoichiometric ratio. This material belongs to the family of metal-semiconductor compounds and appears to be primarily of research interest, as it is not widely established in mainstream industrial applications. The specific combination of these elements suggests potential applications in thermoelectric devices, photovoltaic absorber layers, or optoelectronic components where the tunable band structure of multinary semiconductors could offer advantages over simpler binaries.

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.
