▎ 摘　　要

NOVELTY - Heterojunction photoelectric detector comprises silicon carbide, single-layer graphene, gallium oxide and electrode. The single layer graphene is set between the silicon carbide and the gallium oxide and connected with two electrodes. USE - The heterojunction photoelectric detector is useful for detecting ultraviolet sun blind area under complex infrared and visible light background interference and in national defence, ultraviolet astronomy, and ultraviolet light communication technology. ADVANTAGE - The heterojunction photoelectric detector has high response speed, high mobility, high light-dark current ratio, popularization and application value. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing heterojunction photoelectric detector.
