Al1 As1
semiconductor· Al1 As1
Aluminum arsenide (AlAs) is a III-V semiconductor compound commonly used in optoelectronic and high-frequency electronic devices. It serves as a key material in heterojunction structures, quantum wells, and integrated circuits where its direct bandgap and lattice-matching properties with gallium arsenide (GaAs) enable precise control of electron transport and light emission. AlAs is notable for its role in advancing microelectronics and photonics, particularly in applications requiring high electron mobility and thermal stability at elevated temperatures.

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.
