(a) Projected band structure of 5–7 BN calculated by DFT, inset: the wave functions for the states from B1 and B2. (b) PDOS for B atoms and N atoms. The colors of the energy bands in (a) correspond to the colors of the projected atomic orbitals in (b). (c) Total Dirac points in the first Brillouin zone. (d) The 3D band structures for D1 and D2.
