▎ 摘　　要

NOVELTY - The UV detector has silicon oxide/silicon substrate (4) that includes graphene layer (2) coated on silicon carbide nanowire (1). Two electrodes (3) are arranged on both ends of graphene layer, and back side of substrate is arranged with back gate electrode (5). A lead wire (6) is passed on ends of electrodes and back gate electrode. USE - UV detector of graphene coated silicon carbide nano wire. ADVANTAGE - The UV detector having micro-cavity structure enhances mutual effect of light, inhibits photon-generated carrier, and promotes transfer efficiency of photon-generated carrier with excellent electron transporting characteristics. DESCRIPTION OF DRAWING(S) - The drawing shows longitudinal cross-sectional views of the UV detector.
