Figure 2

Equilibrium structures of the (a) 5/7(S), (b) 5/7(M), and (c) 8 atom cores in the model Σ = 7 boundary. In each structure, two pairs of solid and dotted lines denote the pairs of bonds used to measure the relative angles. The angle of each core structure in both the equilibrium and strained states (d). The wrong bonds in both 5/7 atom cores are marked with double-headed arrows in (a,b). The colored lines in (a)–(c), and the colored symbols in (d), denote the core type: red = 5/7(S), green = 5/7(M), and blue = 8 atom cores.
