| Research Abstract |
Electrical conduction property of graphene originated in local structures, such as the edge of ribbons, was verified using multiple-probe atomic force microscopes to promote the development of graphene devices. Increase of the resistivity by electron scattering at edges was confirmed in the ribbon of monolayer graphene exfoliated on a silicon dioxide film. Moreover, in a graphene formed on a vicinal silicon carbide surface by the sublimation method, which is expected as a template method to form large-area graphene, it turned out that the step part has more than ten times as much as conventional graphene, specifying the challenges for device application.
