GaAs is a semi-conductor material with excellent performance characteristics including direct band gap, high electron mobility, high-frequency low noise, and high conversion efficiency. The RF devices produced with GaAs substrates are commonly used in wireless communication applications, including wireless networks (WLAN), mobile communication, 4G/5G base stations, satellite communications, and WiFi communications. With the development of mini-LED and micro-LED, red light LEDs produced with GaAs substrates are increasingly used for display screens and in AR/VR.
OST Photonics offer 2”, 3”, 4”, 6” GaAs wafers grown by VGF/LEC technology. There are five types of GaAs materials for you to choose from: semi-insulating GaAs (undoped), N-type GaAs (Si doped), semi-insulating GaAs (Cr doped), N-type GaAs (Te doped) and P-type GaAs (Zn doped). The thickness can be customized according to your requirements. In addition, customized GaAs substrates are also available upon requests.
