Gallium arsenide can be made into semi-insulating high-resistance materials with resistivity more than 3 orders of magnitude higher than silicon and germanium, which are used to make integrated circuit substrates, infrared detectors, gamma photon detectors, etc. Because its electron mobility is 5 to 6 times greater than that of silicon, it has important applications in the manufacture of microwave devices and high-speed digital circuits. Gallium arsenide made of gallium arsenide can be made into semi-insulating high-resistance materials with resistivity of more than 3 orders of magnitude higher than silicon and germanium, which are used to make integrated circuit substrates and infrared detectors.
