We study the Fourier transform of the local density of states (LDOS) ingraphene in the presence of a single impurity at high magnetic field. We findthat the most pronounced features occur for energies of the STM tip matchingthe Landau level energies. The Fourier transform of the LDOS shows regions ofhigh intensity centered around the center and the corners of the Brillouin zone(BZ). The radial intensity dependence of these features is determined by theform of the wavefunctions of the electrons in the quantum Hall regime.Moreover, some of these regions break rotational symmetry, and their angulardependence is determined by the chirality of the graphene electrons. For thezeroth Landau level, the ratio between the features at the corners and centerof the BZ depends on the nature of the disorder: it goes to zero for potentialdisorder, and is finite for hopping disorder. We believe that a comparisonbetween our analysis and experiments will help understand the form of thequasiparticle wavefunction, as well as the nature of disorder in graphene.
