The geometric structures of graphene nanoribbons, such as the width (Ny) and the period (Ry) of the ribbons, greatly determine the band structures. Furthermore, the stacking arrangement between graphene nanoribbons and monolayer graphene also plays an important role in low-energy states. Energy gaps caused by AA- and AB-stacking are dependent on Nys and Rys differently. These geometric structure effects can be well identified by the density of states. © 2011 Elsevier B.V.
