Edge plasmons in graphene nanostructures

Edge plasmons in graphene nanostructures:
Author(s): Weihua Wang, Peter Apell, and Jari Kinaret
Plasmon modes in graphene are influenced by the unusual dispersion relation of the material. For bulk plasmons this results in a n^1/4 dependence of the plasma frequency on the charge density, as opposed to the n^1/2 dependence in two-dimensional electron gas (2DEG); yet, bulk plasmon dispersion in gr...
