· Cu2 C2 S2 N2

Cu₂C₂S₂N₂ is an experimental mixed-anion semiconductor compound combining copper with carbon, sulfur, and nitrogen in a single crystal lattice. This material belongs to an emerging class of quaternary semiconductors designed to enable bandgap engineering and multi-functional properties not achievable in binary or ternary systems. Research into such compounds targets next-generation photovoltaics, optoelectronics, and catalytic applications where tunable electronic structure and heteroatom doping can improve light absorption, charge transport, or surface reactivity compared to conventional III–V or II–VI semiconductors.

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.
