Figure 7
A plot of peak splitting [\Delta s] versus 1/L (both in units of Å−1). The peak splittings are taken as the average for the 008, 0 0 14 and 0 0 20 reflections from thin films of SBTN. The experimental data points (red crosses) are calculated from data published by Zurbuchen et al. (2007BB59). The theoretically predicted data points (open symbols) and the corresponding straight lines are calculated using the OPB theoretical model discussed in the main text, with the structural data published by Shimakawa et al. (1999BB46) and OPB parameters [\phi] = 53° and [\delta] = 4.5 Å, as published by Zurbuchen et al. (2007BB59). The blue points correspond to a narrow normal distribution for [f\left(L \right)], such that [{\sigma _L}/{\mu _L}] = 0.05, while the purple points correspond to a broader distribution for [f\left(L \right)], such that [{\sigma _L}/{\mu _L}] = 0.2.
