摘要
In this study, we investigated the one-dimensional transport in armchair graphene nanoribbons (AGNRs) modulated by a magnetic barrier structure. The conductance as a function of Fermi energy shows a step-like increase by the height of 4e(2)/h with characteristic oscillations associated with tunneling resonances. The results turn out to be sensitive to the boundary conditions. In addition, we discussed bound states which exist in the region of the magnetic structure. (C) 2009 Elsevier B.V.
