Effects of edge on graphene plasmons as revealed by infrared nanoimaging
We used scattering-type scanning near-field optical microscopy (s-SNOM) to investigate the plasmonic properties of edges in well-defined graphene nanostructures
including sharp tapers
nanoribbons and nanogaps
which were all fabricated via the growth-etching chemical vapor deposition (GECVD) method. The obtained near-field images revealed the localized
plasmon modes along the graphene nanoribbon; these modes strongly depended on the size of the graphene pattern
the angle of the tapered graphene and the infrared excitation wavelength. These interesting plasmon modes were verified by numerical simulations and explained by the reflection
and interference of electromagnetic waves at the graphene–SiO
2
edge. The constructive interference at the graphene nanogap caused by charge accumulation was demonstrated for the first time. Using the infrared nanoimaging technique
greater plasmon broadening was observed in the zigzag edge than in the armchair edge. Our study suggests that graphene edges should be separated by an effective working distance to avoid the overlapping of localized plasmon modes
which is very important for the design of graphene-based plasmonic circuits and devices.
