Web‘GaAs’ is shorthand for Gallium Arsenide, a compound made up of two elements, and the semiconductor used to manufacture GaAs wafers. GaAs is used as a direct bandgap semiconductor, which in layman’s terms, simply means that particles such as electrons can pass through components much quicker and with very little interference .
