Edge States and Stacking Effects in Nanographene Systems
Bilayer graphene nanoribbon with a zigzag edge is investigated with the tight binding model. Two stacking structures, α and β, are considered. The band splitting is seen in the α structure, while the splitting in the wave number direction is found in the β structure. The local density of states in the β structure tend to avoid sites where inter-layer hopping interactions are present.
