Conductance through disordered graphene nanoribbons: Standard and anomalous electron localization
Ioannis Kleftogiannis, Ilias Amanatidis, Victor A. Gopar
Conductance fluctuations produced by the presence of disorder in zigzag and armchair graphene nanoribbons are studied. We show that quantum transport in zigzag nanoribbons takes pl…
Multifractal zero mode for disordered graphene
I. Kleftogiannis, S. N. Evangelou
Off-diagonal disorder with random hopping between the sublattices of a bipartite lattice is described by a Hamiltonian which has chiral (sub-lattice) symmetry. The energy spectrum…
Edge states versus diffusion in disordered graphene flakes
Ioannis Kleftogiannis, Ilias Amanatidis
We study the localization properties of the wavefunctions in graphene flakes with short range disorder, via the numerical calculation of the Inverse Participation Ratio() and…
Critical level-statistics for weakly disordered graphene
H. Amanatidis, I. Kleftogiannis, D. E. Katsanos +1
In two dimensions chaotic level-statistics is expected for massless Dirac fermions in the presence of disorder. For weakly disordered graphene flakes with zigzag edges the obtained…
