▎ 摘　　要

NOVELTY - Gallium oxide solar blind ultraviolet detector with graphene and polar J-TMD insertion layer comprises a substrate (1), a first gallium oxide channel layer (2), a graphene layer (3), a metal nano-structure layer (4) and a second gallium oxides channel layer(5), further comprising a two-dimensional layered material interface modification layer (6) with a source electrode (7) located on the upper surface of the second-gallium oxide channel layer, and a drain electrode (8) located at the end of the metal drain electrode opposite to the source electrode. The graphene layer is a single layer modified by metal nano structure layer, double-layer or multi-layer graphene. The metal nano structural layer is metal nano particles arranged on the graphene thin film layer combined with the periodic grid of graphene hexagonal structure characteristic flatly spread between the metal nano particle. USE - Gallium oxide solar blind ultraviolet detector with graphene and polar J-TMD insertion layer for use in fire early warning, target identification and information communication. ADVANTAGE - The detector can effectively improve the carrier mobility and light absorption capability, reduce the surface contact the resistor, improve the response degree of the ultraviolet detector and the response speed level, has small exciton binding energy, high mobility and so on, characteristics heterojunction with gallium oxide can effectively inhibit interface exciton recombination, and improve the transfer speed, and can promote the carrier diffusion upwards. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a preparation method of gallium oxide solar blind ultraviolet detector with graphene and polar J-TMD insertion layer. DESCRIPTION OF DRAWING(S) - The drawing shows a structural diagram of a gallium oxide solar blind ultraviolet detector with graphene and polar J-TMD insertion layer (Drawing includes non-English language text).
