Large-scale graphene electronics requires lithographic patterning of narrow graphene nanoribbons for device integration. Here, we devised a gas phase chemical approach to etch graphene from the edges without damaging its basal plane.
Our controlled etching method opens up a chemical way to control the size of various graphene nano-structures beyond the capability of top-down lithography. Geim, A. The rise of graphene. Nature Mater. Graphene: status and prospects.

DOI: We developed a chemical route to produce graphene nanoribbons GNR with width below 10 nanometers, as well as single ribbons with varying widths along their lengths or containing lattice-defined graphene junctions for potential molecular electronics. The GNRs were solution-phase-derived, stably suspended in solvents with noncovalent polymer functionalization, and exhibited ultrasmooth edges with possibly well-defined zigzag or armchair-edge structures.
