ABSTRACT
The essential electronic properties, band structures and density of states, of the sliding bilayer graphene systems are thoroughly explored by the tight-binding model, in which the position-related interlayer hopping integrals under the empirical formula are more convenient for the numerical calculations. The energy loss spectra of the sliding bilayer systems could provide diverse screened phenomena, in which the 2D plasmon modes might be damped by the various electron–hole pair excitations. There are certain significant studies on the diversified essential properties of the sliding bilayer graphene systems. The previous theoretical works show that the intermediate configurations between AA and AB stackings exhibit an anomalous optical phonon splitting and an unusual electronic transmission. The sliding bilayer systems obviously exhibit the geometry- and doping-diversified Coulomb excitation phenomena by illustrating the rich-phase diagrams. Obviously, for the sliding pristine bilayer systems, the Coulomb and electromagnetic wave perturbations present rather different bare response functions, mainly due to the nonvertical and vertical scatterings.
