Impurity induced Dirac point smearing in graphene
It is shown that in a two-dimensional system with the linear dispersion a resonance is present in the Dirac
 point vicinity, when the impurity perturbation magnitude exceeds the bandwidth. The corresponding spectrum

| description | It is shown that in a two-dimensional system with the linear dispersion a resonance is present in the Dirac
point vicinity, when the impurity perturbation magnitude exceeds the bandwidth. The corresponding spectrum
rearrangement, which follows at a certain critical impurity concentration, results in the square root dependence
of the concentration smearing region width on the concentration. If the perturbation magnitude
does not exceed the bandwidth, or the critical concentration is not reached, the concentration smearing region
width remains exponentially small.
