Gallium Arsenide GaAs wafers are principally used to fabricate electronic devices such as infrared light-emitting diodes, laser diodes, optical windows, field-effect transistors FETs, linear of digital ICs and solar cells. GaAs components are useful in ultra-high radio frequencies and fast electronic switching application, weak-signal amplification applications. Furthermore, Gallium Arsenide substrate is a ideal material for the manufacture of RF components, microwave frequency and monolithic ICs, and LEDs devices in optical communications and control systems for its saturating hall mobility, high power and temperature stability.
