Magnetic Properties of Gated Graphene Nanostructures

Part of the NanoScience and Technology book series (NANO)


In this chapter we describe magnetic properties of graphene quantum dots and rings with broken sublattice symmetry using the TB+HF+CI methodology. The broken sublattice symmetry leads to the existence of a shell of degenerate levels at the Fermi level. We discuss how the electronic and magnetic properties of GQDs depend on the filling of the shell in triangular graphene quantum dots (TGQD), how they can be controlled by electric field in bi-layer TGQDs and how they can be detected in Coulomb and Spin Blockade transport experiments.
