Plots of wave functions of LUMO and HOMO levels. (a) Plot of the wave function of the LUMO level in TCNQ/graphene system at Γ point. LUMO is delocalized over π orbitals of graphene. (b) Plot of the wave function of the HOMO level shows strong localization on TCNQ molecule. Red and green lobes are of equal amplitude and opposite sign.
