NOVELTY - Fabricating graphene based nanostructure involves depositing catalyst onto a substrate to form catalytic layer; nanopatterning the catalytic layer to form a nanotemplate; and depositing graphene onto the nanotemplate to form the graphene based nanostructure. USE - For fabricating graphene based nanostructure such as graphene nanoribbon (GNR) or graphene nanonetwork (GNN) (claimed) used in electronic devices, super-strong composite materials, and energy generation and storage. ADVANTAGE - The fabrication method is simple and cost-effective, can be scaled up, and at the same time can produce controllable and reliable thin layers; and is more efficient and consistent. The present thin layer fabrication method has the ability to mass produce graphene nanostructures. Prior art techniques produce a dissatisfactory yield, however because the present method uses nanotemplates, the percentage yield is improved. Thus GNRs and GNNs can be produced much more efficiently.
