First-principles calculations are employed in the study of the
electronic and quantum transport properties of hexagonally shaped boron
nitride (h-BN) clusters embedded in either zigzag or armchair graphene
nanoribbons. Chemical doping of the h-BN cluster was taken into
consideration by using carbon atoms to replace either the boron
(B24N27C3) or the nitrogen (B27N24C3) sites in the central ring. While
the quantum conductance of the system with zigzag edges is found to be
spin-dependent, it was observed that the system with an armchair edge
requires an electron imbalance in order to show a spin-dependent
conductance. Furthermore, the possibility of molecular adsorption onto
these doped systems is studied. The effects of the attached molecules to
the quantum conductance shows the potential of these hybrid systems for
molecular sensing applications.
