Large on-site potential differences in the nitrogen-doped bilayer graphene surface calculated by DFT.

(a,b) Structure of bilayer graphene with graphitic-N calculated by DFT. The colour of the atom represents the on-site potential with respect to the carbon of pristine graphene. Graphitic N is the atom labelled 7 in (b). (c) Calculated bond lengths and relative on-site potentials at the positions labelled from 1 to 12 in (b).
