Electronic structure of defects on the surface of graphite

We have investigated the electronic structure of isolated uncharged defects (carbon vacancies, replacement of a carbon atom by an atom of boron or nitrogen) on the (0001) surface of graphite. It is shown that the change in the electronic subsystem of the graphite surface can be determined both by short-range covalent interactions of the defect with carbon atoms and by the extended perturbation of the surface by the charge of the defect. The ranges of action of these two components of the potential of the defect have been estimated. We calculated C-C bond orders for a graphite surface containing a defect.
