Breakdown field of si
WebSiC can withstand a voltage gradient (or electric field) 5 to 20 times greater than Si or GaAs without undergoing avalanche breakdown . This high breakdown electric field enables the fabrication of high-voltage and high-power devices. Additionally, it allows the devices to be placed very close together, providing high device packing density for ... WebThe breakdown electric field is the theoretical maximum value of the electric field and the withstand voltage is equal to the area of the triangle indicated by the width of the depletion layer and the electric field. Since the breakdown electric field of SiC is about 10 times that of Si, SiC SBD with high withstand voltage can be formed.
