  • Publication number: 20130183625
    Abstract: A method for fabricating patterned graphene structures, which adopts a photolithographic etching process to fabricate patterned graphene structures, comprises steps: providing a substrate; forming a catalytic layer on the substrate; forming a carbon layer on the catalytic layer; heating the carbon layer to a synthesis temperature to form a graphene layer. A photolithographic etching process is performed on the catalytic layer before formation of the carbon layer. Alternatively, a photolithographic etching process is performed on the carbon layer before heating. Alternatively, a photolithographic etching process is performed on the graphene layer after heating. Compared with the laser etching process, the photolithographic etching process is suitable to fabricate large-area patterned graphene structures and has advantages of high productivity and low cost.
