▎ 摘　　要

NOVELTY - The detector has a titanium dioxide nanometer column array (2) arranged on an upper surface of a FTO glass (1). The nanometer column array is in an ohmic contact with the FTO glass. A top end of the nanometer column array is formed with a graphite film (3). A lead electrode (4) is in the ohmic contact with the graphene film. The nanometer column array is defined as n-type titanium dioxide, where thickness of the FTO glass is determined for about 2.2 mm. The nanometer column array is made of a hydrothermal element, where height of the nanometer column array is about 1 to 2 m. USE - Graphene/titanium dioxide nanometer column array Schottky UV photovoltaic detector. ADVANTAGE - The detector can increase material surface area of the nanometer column array to utilize the graphene material with high light transmittance, and, and enhances absorption of the light and response of the light, has low resistivity, better characteristics, high light absorption ability, better UV sensitive induction and high electromagnetic interference resistance. DETAILED DESCRIPTION - The graphene film is defined as an intrinsic graphene film. An INDEPENDENT CLAIM is also included for a graphene/titanium dioxide nanometer column array Schottky UV photovoltaic detector preparation method. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of a graphene/titanium dioxide nanometer column array schottky uv photovoltaic detector.
