(a) Energy band and (b), (d)-(e) isosurfaces of electron densities of the three states associated with the trimerized pyridine-type defects in graphene (see text). (c) Energy band and (f) isosurface of electron density of tetramerized pyridine-type defects in graphene. The isosurface value of electron density is set to 0.03 electrons/Å3. The Fermi energy is set to zero. The dashed lines show the supercell. Reproduced with permission from [47], copyright 2011, the American Physical Society.
