Query: Edge and surface plasmons in graphene nanoribbons   We report on nano-infrared (IR) imaging studies of confined plasmon modes
inside patterned graphene nanoribbons (GNRs) fabricated with high-quality
chemical-vapor-deposited (CVD) graphene on Al2O3 substrates. The confined
geometry of these ribbons leads to distinct mode patterns and strong field
enhancement, both of which evolve systematically with the ribbon width. In
addition, spectroscopic nano-imaging in mid-infrared 850-1450 cm-1 allowed us
to evaluate the effect of the substrate phonons on the plasmon damping.
Furthermore, we observed edge plasmons: peculiar one-dimensional modes
propagating strictly along the edges of our patterned graphene nanostructures.
