 abstract = {The zigzag edges of single-or few-layer graphene are perfect
one-dimensional conductors owing to a set of gapless states that are
topologically protected against backscattering. Direct experimental
evidence of these states has been limited so far to their local
thermodynamic and magnetic properties, determined by the competing
effects of edge topology and electron-electron interaction. However,
experimental signatures of edge-bound electrical conduction have
remained elusive, primarily due to the lack of graphitic nanostructures
with low structural and/or chemical edge disorder. Here, we report the
experimental detection of edge-mode electrical transport in suspended
atomic-scale constrictions of single and multilayer graphene created
during nanomechanical exfoliation of highly oriented pyrolytic graphite.
The edge-mode transport leads to the observed quantization of
conductance close to multiples of G(0) = 2e(2)/h. At the same time,
conductance plateaux at G(0)/2 and a split zero-bias anomaly in
non-equilibrium transport suggest conduction via spin-polarized states
in the presence of an electron-electron interaction.},
