英文摘要	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 newstructure, laser can trigger the device convenientlyby irradiate the electrodeface directly. Acircuit without load resistor is used to test the performance of device, and a switch is triggered by Nd:YAG 532-nm laser (10-ns full-width at half-maximum). Results show that the minimum on-state resistance is 7.5 Omega at an illumination density of 18.2 MW/cm(2), and the breakdown voltage is 12 kV (breakdown electric field is 260 kV/cm). In particular, the optical utilization efficiency of laser energy and the minimum on-state resistance performance are significantly improved in this new vertical geometry photoconductive switch by the AZO film and mirror reflector.
