OPTICALLY CONTROLLED SILICON CARBIDE PHOTOCONDUCTIVE SWITCH

摘要

An optically controlled silicon carbide (SiC) photoconductive switch is provided. The switch comprises a photoconductive wafer and electrodes. The photoconductive wafer is a silicon carbide wafer, and has following well-polished crystal planes: at least one (100) m plane, at least two (110) a planes, wherein the (100) m plane or the (110) a planes are planes towards light and optically connected to an initiated optical source, and the electrodes have good electricity performance with the (110) a planes or the (100) m plane. When the (100) m plane is used as the plane towards light, the electrodes electrically connect to the (110) a planes; and when the (110) a planes are used as the planes towards light, the electrodes electrically connect to the (100) m plane.
