Graphene Patterning and Lithography Employing Laser/Electron-Beam Reduced Graphene Oxide and Hydrogenated Graphene

Having discovered that graphene oxide (GO) films get reduced to graphene when subjected to laser or electron beam irradiation, we have carried out graphene patterning and nanolithography starting with pure GO and GO mixture with gold and platinum salts. Patterning has also been carried out with hydrogenated graphene which upon laser irradiation reverts back to graphene giving out hydrogen.
