(color online) Band structures, transmission spectra and energy gaps of simple aGNRs (2M = 2). Panels (a) and (b) show the band structure and transmission of a simple aGNR with N = 6, panels (c) and (d) the band structure and transmission of a simple aGNR with N = 8, panel (e) displays the band gaps of aGNRs with uniaxial strain σ in x direction. In panels (a) and (c), a is the period of the supercell and , where a0 is the lattice constant of aGNR.
