Electronic structures from tight binding approximation.
Band structures for a set of tight binding parameters 
in the unit of eV. The regions in the green boxes in (a) is highlighted in (b). The red dashed bands are obtained from the perturbation theory. For two lowest bands, we plot their OAM (blue) and SAM (red) structures in (c) and (d) each.
