Abstract

The band structures and optical properties of AA-stacked multilayer graphenes are calculated by the tight-binding model and gradient approximation. For a n_L-layer AA-stacked graphene, there are n_L peaks at both low and middle frequencies. The threshold energy of odd-layer graphene is much lower than that of even-layer graphene for n L < 10. The differences in the electronic structures and optical properties between the odd and even layers are reduced with increasing n_L. When n_L grows to 30 (200), the spectra of 2D graphene are almost identical to those of 3D graphite at middle (low) frequencies.
