Performance of a Vertical 4H-SiC Photoconductive Switch With AZO Transparent Conductive Window and Silver Mirror Reflector

A new vertical geometry photoconductive switch device based on vanadium compensated 4H Silicon Carbide (4H-SiC) is presented with the structure of aluminum doped ZnO (AZO) transparent conductive window on the top of 4H-SiC and a silver mirror reflector on the backside. For this new structure, laser can trigger the device convenientlyby irradiate the electrode face directly. A circuit without load ...
