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, b...

description 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.
