▎ 摘　　要

NOVELTY - An article comprises a graphene layer (42) having work function (a) and a metal oxide film (50) having work function greater than work function (a), formed on the graphene layer. The electrons are transferred from graphene layer to the metal oxide film, to form a hole-accumulation layer on the graphene layer. USE - Article e.g. photodetector and device (both claimed) e.g. graphene-based nanoelectronic device, graphene-based p-n junction diode rectifier and graphene-based field effect transistor. ADVANTAGE - The optical has excellent ferromagnetic properties. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) method of doping graphene; (2) photodetector; and (3) device. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of article. Epitaxial graphene structure (40) Graphene layer (42) Top surface (43) Metal oxide film (50) Thin film structure (60)
