Local density of states in disordered graphene
Klaus Ziegler, Balázs Dóra, Peter Thalmeier
We study two lattice models, the honeycomb lattice (HCL) and a special square lattice (SQL), both reducing to the Dirac equation in the continuum limit. In the presence of disorder…

On the effect of weak disorder on the density of states in graphene
B. Dóra, K. Ziegler, P. Thalmeier
The effect of weak potential and bond disorder on the density of states of graphene is studied. By comparing the self-consistent non-crossing approximation on the honeycomb lattice…
