Figure 1
Experimental diffuse scattering and its compositional dependence. (a)–(e) Symmetry-averaged hk0 layers of the experimental single-crystal diffuse scattering patterns for KCl1–xBrx with x = (a) 0.0, (b) 0.2, (c) 0.5, (d) 0.8 and (e) 1.0. Note the lines of diffuse scattering that connect neighbouring Bragg peaks along 〈100〉 directions. Selected Brillouin zone boundaries are shown schematically as white lines in panel (e), together with the position of key high symmetry positions, denoted using Bradley–Cracknell notation (Bradley & Cracknell, 1972  ). (f) Compositional dependence of the width of the Γ–X diffuse scattering feature determined using Lorentzian fits to the scattering profile measured along the W–Δ–W cut [orange line in panel (e)]. In the virtual crystal (mean-field) limit, the scattering function is expected to vary linearly with composition (dashed line). Further details of the fitting process are given as supporting information. |
