Disorder effect on the density of states in Landau quantized graphene

We have studied the effect of gaussian potential (on-site) and unidirectional bond disorder on the density of states (DOS) of Landau quantized graphene. The broadening of the Landau levels weakly depends on energy and the symmetry of the disorder except at the Dirac point. There, bond disorder enh...

We have studied the effect of gaussian potential (on-site) and unidirectional bond disorder on the density of states (DOS) of Landau quantized graphene. The broadening of the Landau levels weakly depends on energy and the symmetry of the disorder except at the Dirac point. There, bond disorder enhances significantly the peak in the DOS. For stronger disorder, Landau quantization becomes irrelevant, the discrete structures from Landau levels disappear, and we recover the zero field DOS.
We are grateful for useful discussions to K. Ziegler and P. Thalmeier. This work was supported by the Hungarian Scientific Research Fund under grant number OTKA TS049881 and K 72613.
