a The initial geometry of a neutral [(C6F5)4B] molecule adsorbed onto 7 × 7 graphene as the structure model for DFT calculations. b Isosurfaces of the charge-redistributed [(C6F5)4B]−−7 × 7 graphene complex. Yellow and blue isosurfaces correspond to the electron-rich and hole-rich areas, respectively. c Calculated energy-band structure of the [(C6F5)4B]−−7 × 7 graphene complex. The vertical axis shows the relative energy from the Fermi level
