Ab initio Computational Study of Quantum Plasmons in Graphene Nanoflakes

Abstract

We investigate the potential merit in using nanometer-sized graphene flakes as building blocks of twodimensional (2D) quantum metamaterials. The choice of the building blocks is crucial to the design of quantum metamaterials with desired properties, graphene nano-structures being promising candidates towards this end. Thus, they can be grown either by bottom-up chemical synthesis or top-down electronbeam patterning in various shapes, densities, topology, and size, down to the molecular scale. We show that this versatility provides a wide range of parameters to tune the optical properties of graphene-based 2D quantum metamaterials
