▎ 摘　　要

NOVELTY - The method involves laying a first graphene electrode onto a substrate surface (1001), where the first electrode is formed of a carbon-based single-layer material. A block is patterned over an end of the first electrode and portions of the substrate surface (1004), where the block is formed of a visibly transparent material that is deposited into the block at 75 degree Celsius to 125 degree Celsius. A section of the block and exposed sections of the first electrode are masked (1006). A second graphene electrode is laid onto an unmasked section of the block with an end of the second electrode laid onto the substrate surface (1007), where the second electrode is formed of the carbon-based single-layer material. USE - Method for fabricating a visibly transparent UV photodetector of a sunshade device e.g. sunglass and optical element. ADVANTAGE - The method enables controlling chemical reactants provided by source gases and setting system parameters in an epitaxial deposition process, so that depositing atoms arrive at a deposition surface of a semiconductor substrate with sufficient energy to move about on the deposition surface, thus allowing the depositing atoms to be orient to crystal arrangement of atoms of the deposition surface. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a visibly transparent UV photodetector. DESCRIPTION OF DRAWING(S) - The drawing shows a flow diagram illustrating a method for fabricating a visibly transparent UV photodetector.
