· Sc1 Cu2 In1

Sc₁Cu₂In₁ is an intermetallic compound combining scandium, copper, and indium—a research-phase material in the semiconductor and functional materials space. This ternary system has been investigated for potential applications in photovoltaic absorbers, thermoelectric devices, and other semiconductor applications where the electronic structure benefits from the combination of these three elements. While not yet a mature commercial material, compounds in this family are of interest to researchers exploring alternatives to conventional binary semiconductors, particularly where the scandium content may enhance mechanical stability or the copper–indium base offers photochemical activity similar to established copper–indium–gallium selenide (CIGS) thin-film technologies.

Export Control

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.
