Gallium nitride has an electron mobility of 2000 cm^2/Vs, meaning electrons can move over 30% faster than silicon's electrons. 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 ...
