GaAs substrates sun kasu kashi conductive da Semi-insulating, wanda ake amfani da ko'ina a Laser (LD), semiconductor haske-emitting diode (LED), kusa-infrared Laser, jimla da high-ikon Laser da high-ingancin hasken rana bangarori. HEMT da HBT kwakwalwan kwamfuta don radar, microwave, igiyar milimita ko kwamfutoci masu saurin gudu da hanyoyin sadarwa; Na'urorin mitar rediyo don sadarwar mara waya, 4G, 5G, sadarwar tauraron dan adam, WLAN.
Kwanan nan, gallium arsenide substrates suma sun sami babban ci gaba a cikin mini-LED, Micro-LED, da jajayen LED, kuma ana amfani da su sosai a cikin na'urorin sawa na AR/VR.
