We developed a chemical route to produce graphene nanoribbons (GNR) with width below 10 nanometers, as well single ribbons varying widths along their lengths or containing lattice-defined junctions for potential molecular electronics. The GNRs were solution-phase-derived, stably suspended in solvents noncovalent polymer functionalization, and exhibited ultrasmooth edges possibly well-defined zigzag armchair-edge structures. Electrical transport experiments showed that, unlike single-walled...
Graphene is readily p-doped by adsorbates, but for device applications, it would be useful to access the n-doped material. Individual graphene nanoribbons were covalently functionalized nitrogen species through high-power electrical joule heating in ammonia gas, leading n-type electronic doping consistent with theory. The formation of carbon-nitrogen bond should occur mostly at edges where chemical reactivity high. X-ray photoelectron spectroscopy and nanometer-scale secondary ion mass...
