This book reflects the current status of theoretical and
experimental research of graphene based nanostructures, in
particular quantum dots, at a level accessible to young
researchers, graduate students, experimentalists and theorists. It
presents the current state of research of graphene quantum dots, a
single or few monolayer thick islands of graphene. It introduces
the reader to the electronic and optical properties of graphite,
intercalated graphite and graphene, including Dirac fermions,
Berry's phase associated with sublattices and valley degeneracy,
covers single particle properties of graphene quantum dots,
electron-electron interaction, magnetic properties and optical
properties of gated graphene nanostructures. The electronic,
optical and magnetic properties of the graphene quantum dots as a
function of size, shape, type of edge and carrier density are
considered. Special attention is paid to the understanding of edges
and the emergence of edge states for zigzag edges. Atomistic tight
binding and effective mass approaches to single particle
calculations are performed. Furthermore, the theoretical and
numerical treatment of electron-electron interactions at the
mean-field, HF, DFT and configuration-interaction level is
described in detail.
