    Abstract: A photodetector which uses single or multi-layer graphene on a gate oxide layer (12) as the photon detecting layer (14) is disclosed. Multiple embodiments are disclosed with different configurations of the source (8), drain (6) and gate (10) electrodes. In addition, a photodetector array comprising multiple photodetecting elements is disclosed for applications such as imaging and monitoring. An optical waveguide underlying the graphene layer (14) may be embedded into substrate (10) or gate oxide layer (12) in order to channel photons towards graphene layer (14).

    Abstract: Strukturen zum Abschirmen elektromagnetischer Störungen und Verfahren zum Abschirmen eines Objekts vor elektromagnetischer Strahlung bei Frequenzen, die höher als ein Megahertz sind, beinhalten im Allgemeinen das Bereitstellen hoch dotierter dünner Lagen aus Graphen um das abzuschirmende Objekt herum. Die hoch dotierten dünnen Lagen aus Graphen können eine Dotierstoffkonzentration, die höher als > 1e1013 cm–2 ist, die dahingehend wirksam ist, dass die elektromagnetische Strahlung reflektiert wird, oder eine Dotierstoffkonzentration von 1e1013 cm–2 > n > 0 cm–2 aufweisen, die dahingehend wirksam ist, dass die elektromagnetische Strahlung absorbiert wird.

    Abstract: A method for doping a graphene and carbon nanotube thin-film transistor field-effect transistor device to decrease contact resistance with a metal electrode, comprising; selectively applying a dopant to a metal contact region of a graphene and nanotube field-effect transistor device. Also disclosed are graphene and nanotube thin-film, field effect transistors: where the dopant is disposed on the graphene/nanotube layer 140 and the metal electrodes formed thereafter; and where the graphene/nanotube layer is formed over the metal electrodes and the dopant is selectively applied to the areas above the dopant, respectively. The dopant may be one of cerium ammonium nitrate, cerium ammonium sulphate, ruthenium bipyridyl complex or triethyloxonium hexachloro antimonate. The dopant may be provided in a solution, where the solvent may be one of dichloroethane, alcohol or dichlorobenzene. The dopant may be applied to the transistor by immersing the transistor in the solution for a predetermined time.
