Abstract
We compute the tunneling conductance of graphene as measured by a scanning tunneling microscope (STM) with a STM tip and show that the shape of the STM spectra for graphene doped with impurities depends qualitatively on the position of the impurity atom in the graphene matrix. We relate this unconventional phenomenon to the pseudopsin symmetry of the Dirac quasiparticles in graphene and suggest experiments to test our theory.
