Figure 41
Dynamical structure factor S(q,ω) for i-ZnMgSc. Experiment and calculations compared. (a) 1/1 approximant; (b) quasicrystal. The results of the calculation (2/1 approximant for the quasicrystal) are shown in the background distribution. The experimental acoustic curves are given by full dark circles and triangles. Optical branches are represented by the other symbols. The vertical lines indicate the Brillouin zone and pseudo-Brillouin zone boundaries (de Boissieu et al., 2007BB16).
