ABSTRACT
The hexagonal symmetry, AA-stacking configuration and significant interlayer atomic interactions are responsible for the unusual essential properties. The quantized energies have a simple dependence on, so that the magneto-absorption spectra present beating features. The experimental verifications of energy bands, density of states (DOS) and absorption spectra of simple hexagonal graphite can be utilized to determine the critical intralayer and interlayer atomic interactions. The electronic states of a Dirac cone are magnetically quantized into one group of valence and conduction Landau levels (LLs). The study of the magnetic quantization of a Dirac cone in monolayer graphene is the first step to realizing the magneto-electronic properties of graphites. The monolayer system shows isolated symmetric peaks, while bilayer Simple hexagonal stacking displays pair-peak structures. The unique magneto-excitation spectra of simple hexagonal graphite deserve thorough experimental examinations of properties such as the multichannel threshold peak, intraband two-channel peaks, interband double-peak structures and the magneto-optical beating phenomenon.
