ABSTRACT
In this chapter, we shall discuss the electronic structure of graphene and nanotubes, which are topics of great interest due to interesting physics as well as technological applications. For example, graphene provides the first example of “Dirac material” as its low-energy quasi-particles mimic the behavior of fermions described by the Dirac equation. From the technological point of view, these materials offer great potential for fabrication of new devices at the nanometer scale. We shall discuss the electronic structure of graphene in Section 14.2.
