▎ 摘　　要

NOVELTY - The detector has a gallium oxide crystal substrate formed with a first ohmic contact electrode and a second ohmic contact electrode, where the first ohmic contact electrode is grown on a first surface of the gallium oxide crystal substrate. A second surface of the gallium oxide crystal substrate is formed with a needle point shape structure. A graphene layer is formed on the second surface of the gallium crystal substrate. The second ohmic contact electrode is formed in the graphene layer without contact with the surface of the gallium oxide crystal substrate. The gallium oxide crystal substrate is N-type gallium (III) oxide crystal substrate. USE - Gallium oxide-based UV detector. ADVANTAGE - The detector improves response sensitivity and response speed, and can be manufactured by simple steps at low cost. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for manufacturing a gallium oxide-based UV detector. DESCRIPTION OF DRAWING(S) - The drawing shows a sectional view of a gallium oxide-based UV detector.
