“…The generalized model can also be extensible to other layer stacked systems, i.e., AA-, AB-, ABC-stacked FLGs [87][88][89][90][91] and bulk graphite. [57,[92][93][94] Figure Captions …”

“…Furthermore, under an external perpendicular electric field or a uniform perpendicular magnetic field, the main features of the optical properties of the FLGs are strongly modified. [49,56,57] For theoretical studies, the complexity of calculating the optical absorption spectra is solved by the gradient approximation based on the generalized tight-binding model with exact-diagonalization method or effective-mass approximation. The way in which one can control the absorption peaks and selection rules is worthy to be reviewed in detail.…”

“…The low-energy magneto-optical absorption spectrum of SHG is dominated by intraband and interband optical excitations which induce a multi-channel threshold peak, several two-channel peaks, and many double-peak structures [28]. In the magneto-optical absorption spectra of BG, the prominent peaks originate from the interband excitations at both the K and H points.…”

“…The magneto-optical properties are closely associated with the stacking configurations of graphites [28,[31][32][33].

“…SHG possesses very strong k z -dependent energy dispersions with a broad band width about 1 eV, and each LS can be described by a simple relationship with k z [19,25]. Many LSs cross the Fermi level (E F = 0) [19,28]. Moreover, the excitations related to the densely low-lying LSs own wide energy ranges which can overlap for different optical transition channels.…”

The magneto-optical properties of simple hexagonal graphite exhibit rich beating oscillations, which are dominated by the field strength and photon energy. The former has a strong effect on the intensity, the energy range of the beating and the number of groups, and the latter modulates the total group numbers of the oscillation structures. The single-particle and collective excitations are simultaneously presented in the magnetoreflectance spectra and can be precisely distinguished. For the loss function and reflectance, the beating pattern of the first group displays stronger intensities and broader energy range than other groups. Simple hexagonal graphite possesses unique magneto-optical characteristics that can serve to identify other bulk graphites.

The important experimental advances in graphene fabrication and its peculiar transport properties motivated researchers to utilize graphene as a potential basis for the next generation of fast and smart electronic devices. In this article, we investigate the influence of a potential substrate on the transport properties of a biased AA-stacked n-p-n bilayer graphene junction (AA-BLG). Using the Dirac Hamiltonian with the transfer matrix approach we obtain the transmission probabilities and thus the respective conductance. In the presence of the induced mass-term the energy spectrum and the intra-cone transmission drastically change while the inter-cone transmission remains zero. On the other hand, the bias slightly alters the energy spectrum but it significantly affects the transport properties due to its ability to switch on the inter-cone transmission. In addition, we find that Klein tunnelling is attenuated in the presence of the induced mass-term which can improve the carriers confinement in such configurations. Our findings provide possible experimental measurements to determine the interlayer coupling and the induced mass terms in graphene bilayer based on conductance and band structure measurements.PACS numbers:
