GaAs substrates are divided into conductive and semi-insulating, which are widely used in laser (LD), semiconductor light-emitting diode (LED), near-infrared laser, quantum well high-power laser and high-efficiency solar panels. HEMT and HBT chips for radar, microwave, millimeter wave or ultra-high speed computers and optical communications; Radio frequency devices for wireless communication, 4G, 5G, satellite communication, WLAN.<\/p>\n

Recently, gallium arsenide substrates have also made great progress in mini-LED, Micro-LED, and red LED, and are widely used in AR\/VR wearable devices.<\/p>\n<\/p><\/div>\n<\/p><\/div>\n<\/p><\/div>\n<\/p><\/div>\n<\/p><\/div>\n<\/p><\/div>\n
