ABSTRACT
The fundamental magnetoelectronic properties might be solved by the generalized model. The fundamental magnetoelectronic properties might be solved by the generalized model and the effective-mass model and the effective-mass model. The electronic excitations of bilayer graphene under a magnetic field are explored thoroughly using the generalized tight-binding model in conjunction with the modified random-phase approximation. The peak distributions in the layer-dependent polarization functions are drastically changed as the stacking configuration is transformed from AB to AA. The bilayer magnetoenergy loss function, defined by the layer-dependent polarization functions, could provide the dynamically screened response from the highly degenerate degenerate Landau levels involved by the charge carriers on the first and second layers. The transferred-moment-dependent magnetoplasmon frequencies, which are directly obtained from the intensities of energy loss functions, clearly illustrate the spatial collective charge oscillations. In general, the hump-like abnormal q-dependences appear in the AB bilayer stacking, as observed in monolayer graphene.
