· JVASP-75826· GaAsAu

GaAsAu is a compound material system combining gallium arsenide (GaAs) semiconductor with gold, typically employed in thin-film or contact applications rather than as a bulk alloy. This material class appears in research and specialized industrial contexts where the electronic properties of GaAs must interface with the conductivity and stability of gold, making it relevant for hybrid semiconductor device fabrication and metallization schemes.

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.
