Spectrum of pi electrons in bilayer graphene nanoribbons and nanotubes: An analytical approach
2011 (English)In: PHYSICAL REVIEW B, ISSN 1098-0121, Vol. 83, no 3, 035403- p.Article in journal (Refereed) Published
We present an analytical description of pi electrons of a finite-size bilayer graphene within a framework of the tight-binding model. The bilayered structures considered here are characterized by a rectangular geometry and have a finite size in one or both directions with armchair- and zigzag-shaped edges. We provide an exact analytical description of the spectrum of pi electrons in the zigzag and armchair bilayer graphene nanoribbons and nanotubes. We analyze the dispersion relations, the density of states, and the conductance quantization.
