Simulations of two-dimensional intensity maps obtained with model 1 for various values of the disorder parameters. The results for the geometry [the probing beam perpendicular to the in-plane component of the basis vector ] are shown. We assumed and . (a)–(c) Influence of . The dashed lines parallel to the Qz axis indicate the sheets caused by the in-plane correlation of the QD positions. The correlation of the dot position in different layers gives rise to tilted sheets indicated by dash–dotted lines. (d)–(f) Influence of . (g)–(i) Influence of . (j)–(l) Influence of . The symbols P1–P12 denote the sets of disorder parameters given in Table 1. The QDs are assumed to be spherical.
