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...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Summary: | 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.
