ABSTRACT We show that carbon-doped hexagonal boron nitride (h-BN) has extraordinary
properties with many possible applications. We demonstrate that the
substitution-induced impurity states, associated with carbon atoms, and their
interactions dictate the electronic structure and properties of C-doped h-BN.
Furthermore, we show that stacking of localized impurity states in small C
clusters embedded in h-BN forms a set of discrete energy levels in the wide gap
of h-BN. The electronic structures of these C clusters have a plethora of
applications in optics, magneto-optics, and opto-electronics.

    ABSTRACT: In view of experimental reports of ferromagnetic behaviors in the as-prepared defective BN, the effect of B and N vacancies on the magnetic properties and electronic structure of h-BN and r-BN are investigated using first-principles calculations within the generalized gradient approximation (GGA) and GGA+U scheme. The B and N vacancy induces a set of spin-polarized defect states above the valence band and below the conduction band, respectively, resulting in the formation of local magnetic moment. It is noticed that the U correction for 2p electrons plays important role in obtaining spin-polarized ground states of the h-BN and r-BN systems with B vacancy. Furthermore, the magnetic coupling between the moments induced by two B vacancies is long-range ferromagnetic and the coupling can be attributed to the p–p hybridization interaction involving holes, whereas the coupling between the moments induced by two N vacancies is anti-ferromagnetic. The calculated results suggest that the observed d0 ferromagnetism in the as-prepared defective BN should be attributed to the B vacancies.

    ABSTRACT: We show that spin-polarized electron transport can be achieved by the substitutional doping of only one sublattice of graphene by nitrogen or boron atoms. The bipartite character via two sublattices remains persistent in the electronic structures of graphene doped with low concentrations of nitrogens (borons). The delocalized spin-densities induced by the unpaired electrons at substitutional sites permeate only through the sublattice where the nitrogen (boron) atoms belong. For interacting nitrogen (boron) atoms located along the “zigzag” direction and in the same sublattice, the ferromagnetic spin-ordering is favorable, and substitution-induced localized impurity states selectively disturb the spin-polarized π orbital of that same sublattice. The bipartite character of graphene lattice governs the unique properties of two-dimensional hybrid graphene-boron nitride nanostructures.

    ABSTRACT: Based on the first-principles approach, electronic transport properties of different lengths of carbon-doped boron-nitrogen nanowires, capped with two thiols as end groups connected to Au electrodes surfaces, are investigated. The results show that rectifying performance and negative differential resistance (NDR) behaviors can be enhanced obviously by increasing the length. Analysis of Mülliken population, transmission spectra, evolutions of frontier orbitals and molecular projected self-consistent Hamiltonian of molecular orbital indicate that electronic transmission strength, charge transfer and distributions of molecular states change are the intrinsic origin of these rectifying performances and NDR behaviors.
