Owing to its superior electrical properties, such as a wide band gap (3.2 eV) and a high critical electric field (3MV/cm), Silicon Carbide (4H-SiC) is now considered the material of choice for the next generation of power electronics devices.
Gallium Nitride (GaN) and its related AlxGa1-xN ternary alloys have excellent properties (like a wide band gap, a high critical electric field and a high electron saturation velocity) making them suitable semiconductors for high power and high frequency de
