· CuYO2

CuYO₂ is a copper-yttrium oxide semiconductor compound, representing an emerging material in the broader family of transition metal oxides with potential applications in optoelectronic and photocatalytic devices. This is primarily a research-stage material; it has not achieved widespread industrial adoption but is being investigated for its semiconducting properties and potential to enable novel device architectures where copper and yttrium oxides' complementary characteristics could be leveraged. Engineers considering this material would typically be working in advanced research, prototype development, or next-generation semiconductor applications where conventional semiconductors reach performance or cost 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.
