摘要：
Transport properties of an armchair boron-nitride nanoribbon (ABNNR) between two armchair graphene nanoribbons (AGNRs) have been studied using the tight binding approach in the nearest neighbor approximation. The tight biding parameters are obtained by comparing the tight binding bandstructure of pure and doped hexagonal boron-nitride sheet with first-principle calculations. It is shown that by increasing the ribbon width transmission through the system increases. Also the conductance gap has a damping oscillation with the BNNR width. (C) 2011 Elsevier B.V.
