Image of FIG. 1.
FIG. 1.

(Color online) Armchair-edge nanostrip with imperfect edges. (a) A single perfect edge (solid lines) is deformed by adding or removing pairs of carbon atoms with different probabilities, thereby generating an imperfect edge with defects (dashed lines). (b) An example of a nanostrip with imperfect edges.

Image of FIG. 2.
FIG. 2.

(Color online) Conductance of semiconducting armchair-edge graphene nanostrips with edge defect probability: (a) and (b) . The widths of the nanostrips are approximately . The lengths of the samples are specified in unit cells (1 unit ) and are approximately 54.5 and in (a) and 218 and in (b). The conductance of the samples can be compared to a nanostrip without defects, shown as solid.

Image of FIG. 3.
FIG. 3.

(Color online) Half amplitude localization lengths of armchair-edge graphene nanostrips with edge defect probability: (a) and (b) . The solid curves represent the conductance of a defect-free nanostrip and exhibit a band gap that can be estimated by Eq. (2).
