Abstract

An electrical or electronic device is disclosed. In some embodiments, an electrical device includes a single-layer graphene part extending in a lateral direction and a multi-layer graphene structure laterally contacting the single-layer graphene part. The electrical or electronic device further includes a graphite part in contact with a surface of the multi-layer graphene structure. In other embodiments, an electrical device includes a graphene part extending in a lateral direction and a graphite part is configured to provide a lateral contact for the graphene part.
