Magneto-electronic properties of the AA- and ABC-stacked graphites

Abstract

In this study, we apply the tight-binding method to magneto-electronic properties of the AA- and ABC-stacked graphites, which are strongly dependent on the interlayer interactions, the magnetic field, and the stacking sequences. First of all, the interlayer interactions induce the significant changes in the energy dispersions, the band symmetry about the Fermi level, the overlap between valence and conduction bands, the band width, and the band-edge states or the symmetry points. Then, the magnetic field induces the Peierls phase in the Bloch functions and thus strongly affects the energy dispersions of the Landau Levels, the subband spacings, the energy width, and the special structures in density of states (DOS). Finally, the stacking sequences dominates over the low-energy band overlap and the anisotropy of energy bands. The effects mentioned above are exactly reflected in the density of state. Here, DOS exhibits the 3D, 2D, and 1D characteristics.
