Gallium Arsenide (GaAs) Wafers
Overview
Gallium Arsenide (GaAs) wafers are a leading material in advanced semiconductor applications due to their superior electron mobility, high frequency, and optoelectronic properties. GaAs is widely used in applications that require fast signal processing, high-efficiency power conversion, and superior light-emitting performance, making it a preferred material for RF devices, solar cells, and optoelectronics.
Product Features
High Electron Mobility
GaAs offers electron mobility up to six times higher than silicon, enabling faster signal transmission and more efficient device performance.
Direct Bandgap
GaAs has a direct bandgap, which allows for efficient photon emission and absorption, making it ideal for optoelectronic devices such as LEDs and laser diodes.
High Temperature Stability
GaAs maintains performance stability at higher temperatures, making it suitable for environments that require robust thermal performance.
Low Noise
GaAs wafers offer low signal noise, which is critical in high-frequency applications such as wireless communication and radar.
