Abstract: "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. Electrical
transport experiments showed that, unlike single-walled carbon nanotubes,
all of the sub-10-nanometer GNRs produced were semiconductors and afforded
graphene field effect transistors with on-off ratios of about 10(7) at room
temperature."
