Gallium oxide devices have approximately 5eV bandgap higher than that of silicon carbide ( 3.3 eV ) or gallium nitride (3.4 eV) which makes it more efficient. Due to the higher band gap, a material can withstand higher electric field and for a given voltage, it makes possible to use a thinner device i.e thinner the device, lower resistance.
