· CdAs2

Cadmium arsenide (CdAs₂) is a III-V compound semiconductor formed from cadmium and arsenic, belonging to the family of binary semiconductors used in specialized optoelectronic and high-frequency applications. Historically explored for infrared detectors, laser diodes, and high-speed electronic devices, CdAs₂ has seen limited commercial deployment compared to more mature compounds like GaAs and InP, largely due to cadmium's toxicity concerns and the superior performance of alternative arsenide semiconductors. The material remains relevant in research contexts for specialized infrared sensing and as a reference compound in semiconductor physics studies, particularly where its specific bandgap or lattice properties offer theoretical advantages over established alternatives.

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.
