Image of FIG. 1.
FIG. 1.

Density of state (DOS) of a -wide and -long edge-disordered (gray) and perfect (black) armchair nanoribbon, normalized to the ribbon length.

Image of FIG. 2.
FIG. 2.

(a) Representation of the disordered graphene nanoribbon used for calculation of Fig. 1. The inset focuses on a detail of a disordered edge. [(b)–(d)] Representation of the squared wave function of states of energy , 0.26, and . The plot is composed of circles localized at the centers of atoms whose area is proportional to occupation probability of the atom.

Image of FIG. 3.
FIG. 3.

(a) Averaged quasi-mobility edge for zigzag, armchair, and mixed edges GNRs with one row of edge disorder as a function of ribbon width. Inset: bandgaps of ideal GNRs. (b) Averaged quasi-mobility edge for zigzag, armchair, and mixed edged GNRs with two rows of edge disorder as a function of ribbon width. Inset: inverse of the averaged quasimobility edge as a function of the ribbon width.
