Bondons on Nano-Ribbons with Stone-Wales Defects

5 BONDONS ON NANO-RIBBONS WITH STONE-WALES DEFECTS 

1 SECOND ORDER EEEECTS OF BONDONS ON GRAPHENIC FRAGMENTS 

FIGURE 1.7 Framed super-cell of grapheme nanoribbonGNR for the pristine condition (a) and after the creation of a single S W defect 5111115 by rotating the diagonal bond between the two circled eaibon atoms (b). Horizontal size L=6 has been ehosen. Bonds crossing the dashed line periodically close the stmeture in both directions (Putz Ori, 2012). 

As in previous topological modeling studies that have been recently devoted to grapheme layers with nanocones (Cataldo et al., 2010), Cgg fullerene stability (Vukicevic et al., 2011) or schwarzitic nanoribbons conformations (De Corato et al., 2012), the topological potential derives from the Wiener index W of the chemical structure (Estrada Hatano, 2010). 

Topological invariants moreover offer an intriguing explicit dependence from system dimensionality D that fixes the leading exponent of the polynomial forms that express the indices as a function of the lattice size in case of D= stmetures like GNR , the following general laws hold W(L) D and being s=2D+l (Ori-Cataldo-Putz, 2011
