WebSep 16, 2013 · Researchers Use Graphene in Photodetectors. In a new graphene-on-silicon photodetector, electrodes (gold) are deposited, slightly asymmetrically, on either side of a silicon waveguide (purple). The asymmetry causes electrons kicked free by incoming light to escape the layer of graphene (hexagons) as an electrical current. WebA photodetector with parallel electrodes was fabricated. As shown in Figure A7a, the SPF on thea glass substrate was deposited by PMMA/graphene. A parallel electrode with a spacing of 220 μm was deposited on graphene using a physical vapor deposition method (see Figure A7b). The photoresponse of the photodetector was measured by a Keithley ...
