The shape of disorder broadened Landau subbands in graphene
arXiv:0810.4475 · doi:10.1103/PhysRevLett.102.056803
Abstract
Density of states (DOS) of graphene under a high uniform magnetic field and white-noise random potential is numerically calculated. The disorder broadened zero-energy Landau band has a Gaussian shape whose width is proportional to the random potential variance and the square root of magnetic field. Wegner-type calculation is used to justify the results.
