A graphene material having a desired shape is easily produced. First, a substrate body 12 is prepared, and a Ni crystal layer 14 is formed on the entire surface of the substrate body 12. Subsequently, the crystal layer 14 is patterned in a zigzag shape by a lithography method to form a catalyst metal layer 16. Next, C atoms are supplied to the catalytic metal layer 16 by a mixed gas of acetylene and argon. Then, the Ni surface is rearranged in the (111) plane, and the supplied C atoms form a hexagonal lattice and graphene grows. Since graphene is formed on the catalyst metal layer 16, it has the same shape as the catalyst metal layer 16, that is, a zigzag shape. Next, square electrodes 18 and 20 are attached to both ends of the zigzag graphene. Thereafter, the catalytic metal layer 16 is dissolved with an acidic solution, and graphene is taken out as the graphene material 10. [Selection] Figure 1 |
