ABSTRACT
An external electric field perpendicular to the graphene plane is an efficient factor in creating diverse fundamental properties. There are a lot of theoretical and experimental studies on the electronic properties, optical absorption spectra, and quantum transports. The screened response functions are greatly modified by an electric field, such as the frequency, strength and number of the prominent plasmon peaks. The bilayer Bernal stacking is suitable for illustrating the electric-field-diversified Coulomb excitation phenomena in AB-stacked layered graphenes; furthermore, the trilayer ABA stacking is investigated in detail. The bare polarization functions are drastically modified by the electric field and transferred momentum. The trilayer ABA stacking is easily modulated by a uniform perpendicular electric field, when compared with the bilayer one. The electronic properties and Coulomb excitations are more sensitive to F. The electric-field-dependent polarization functions exhibit the stacking-enriched bare response spectra.
