a Schematic illustration of selectional graphene nanodisks with different chemical potentials to change chemical potential of central graphene nanodisk. b The extinction spectra of graphene oligomer with the chemical potential of central graphene nanodisk μc2 = 0.5eV and μc2 = 0.6eV. c The extinction spectrum of graphene oligomer with the chemical potential of central graphene nanodisk μc2 = 0.8eV. The inset shows the electric fields (|E|) at the resonance peak
