· CdSiAs2

CdSiAs₂ is a III-V compound semiconductor formed from cadmium, silicon, and arsenic, belonging to the family of ternary semiconductors used in optoelectronic and high-frequency applications. Historically explored for infrared detector windows, solar cells, and microwave devices, this material offers a direct bandgap suitable for photonic applications, though its use remains largely restricted to specialized research and defense applications due to cadmium toxicity concerns and the availability of superior alternatives like GaAs and InP. Engineers considering CdSiAs₂ typically work in niche infrared sensing, space-grade photovoltaics, or millimeter-wave electronics where its specific lattice properties provide advantages, though environmental and health regulations now limit its commercial deployment in most developed markets.

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.
