The CoRiGraph project focuses on graphene nanostructures produced by non‐lithographic techniques on sidewall of pre-etched SiC steps silicon carbide. This technique takes full advantage of the single crystalline SiC substrate. It is scalable as already demonstrated by the fabrication of 10,000 transistors on a single chip. Nanoscopic ribbons have been shown to have remarkable electronic properties: transport data suggest properties. A gap is observed on the graphene ribbon edge and ballistic transport is demonstrated. This suggests smooth edges since disordered-related effects (localization, transport gap) are not observed. These ribbons may be the needed breakthrough in graphene electronics, opening the way for electronics based on ballistic transport and coherent effects, which cannot be realized with conventional semiconductors.
