Abstract:We report on the measurements of electronic transport properties of CVD graphene placed on a pre-patterned substrate with periodic nano trenches. A strong anisotropy has been observed between the transport parallel and perpendicular to the trenches. Characteristically different weak localization corrections have been also observed when the transport was perpendicular to the trench, which is interpreted as due to a density inhomogeneity generated by the potential modulations.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
