概要
- 論文の詳細を見る
The Landau level (LL) spectra in rhombohedral graphite are calculated within the tight-binding model without any perturbation expansion. All significant interlayer atomic interactions are included, up to next-nearest-neighbor graphene layers. The magnetic Hamiltonian matrix is derived and manipulated in a band-like form for numerical efficiency. The results of this diagonalization scheme manifest the effects of lattice symmetry and interlayer interaction in the specific stacking configuration. Three-dimensional character associated with the mirror symmetry of the ABC-stacking configuration is exhibited in the LL spectra.
