Fabrication of graphene nanoribbon arrays by substrate‐controlled cutting of graphene during metal‐assisted etching is demonstrated by Hiroki Ago and co‐workers on page 6562. The proposed method allows for large‐area production of highly dense arrays of aligned nanoribbons from a single graphene film. This is expected to facilitate the large‐scale integration of graphene nanoribbons into electronic...
Dense arrays of aligned graphene nanoribbons (GNRs) are fabricated by substrate‐controlled etching of large‐area single‐layer graphene. An adequate choice of etching substrate and catalyst deposition method allows densities up to 25 nanoribbons μm–1 to be obtained with average widths of 19 nm. The efficacy of the method is evidenced by the high on/off ratios of back‐gated transistors made with these...
