· GeAs

GeAs is a III-V compound semiconductor composed of germanium and arsenic, belonging to the same material family as GaAs and InAs. While less common than its III-V cousins, GeAs is primarily investigated in research settings for optoelectronic and high-frequency applications, particularly where the band gap characteristics or lattice properties offer advantages over conventional semiconductors. The material's potential lies in integrated photonics, infrared detection, and high-speed transistor applications where its electronic properties could enable devices operating at different wavelengths or with improved performance compared to 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.
