FIG. 1.

(Color online) A schematic diagram of graphene/BN (a) and BN/BN (b) bilayers. The cyan, green, and blue represent carbon, boron, and nitrogen atoms, respectively.

FIG. 2.

(Color online) Band structure of (a) graphene/BN and (b) BN/BN bilayers at zero bias. Zero of the energy is set to the valence band maximum. The inset in (2a) shows the bandgap near the K point of graphene/BN bilayer.

Image of FIG. 3.
FIG. 3.

(Color online) (a) Total DOS and (b) PDOS of 2pz orbitals for graphene/BN bilayer at an applied electric field, E = 0. The energies are subtracted from the Fermi level E_F (−5.525 eV) and a factor of 0.015 used for broadening the DOS.

Image of FIG. 4.
FIG. 4.

(Color online) (a) Total DOS and (b) PDOS of 2pz orbitals for graphene/BN bilayer at an applied electric field, E ≠ 0. The energies are subtracted from the Fermi level E_F (−7.052 eV) and a factor of 0.015 used for broadening the DOS.
