FIG. 1.

Z(A)GNR (a, W) superlattice models, where a is the neck width, and W the ribbon width. (a) For ZGNR (2, 6), (b) for AGNR (3, 12), and (c) for AGNR (4, 12). The dotted box represents the supercell.

FIG. 2.

Under nonmagnetic state, band structures (a) and transmission spectra (b) of the perfect ZGNR (6) and the punched ZGNR(a, W) with neck widths a = 2,3, and 4. Z represents the case of the perfect ZGNR (6). (c) and (d) Bloch states for ZGNR (6) and ZGNR(a, 6) (a = 2,3, 4) at crossing points of subbands and Fermi level with k = 0.895, 0.415, 0.505, and 0.545 by setting ΓX = 1.0, respectively.

FIG. 3.

At AFM state, band structures (a) and transmission spectra (b) of the perfect ZGNR (6) and the punched ZGNR(a, W) with neck widths a = 2,3, and 4. Z represents the case of the perfect ZGNR (6). (c) and (d) Bloch states for ZGNR (6) and ZGNR(3, 6) at conduction band minimum and valence band maximum, respectively.

FIG. 4.

Band structures and transmission spectra. (a) and (b) ((c) and (d), and (e) and (f)) for the perfect AGNR (16) (AGNR(12), and AGNR(14)) and the punched AGNR(a, 16) (AGNR(a, 12), and AGNR(a, 14)) (a = 2,3, and 4) with ribbon widths satisfying W = 3p + 1(W = 3p, and W = 3p − 1), respectively. The changing regularities of their electronic properties are some different. Labeled A represents the case of the perfect AGNRs
