  • GaN vs SiC Silicon Carbide and Gallium Nitride Compared

    Silicon carbide however has an electron mobility of 650 cm 2/Vs which means that silicon carbide s electrons are slower moving than both GaN and silicon s. With such elevated electron mobility GaN is nearly three times more suitable for high-frequency applications. Electrons can move through a gallium nitride semiconductor much faster than SiC.
