Figure 8
Simulations of two-dimensional intensity maps obtained with model 1 for various values of the disorder parameters. The results for the $[\bot]$ geometry [the probing beam perpendicular to the in-plane component of the basis vector $[{\bf a}^{(3)}]$ ] are shown. We assumed $[\sigma^{(1)}_{x} = \sigma^{(1)}_{y} = \sigma^{(2)}_{x} = \sigma^{(2)}_{y}]$ and $[\sigma^{(1)}_{z} = \sigma^{(2)}_{z}]$ . (a)-(c) Influence of $[\sigma^{(1,2)}_{x,y}]$ . The dashed lines parallel to the Q_z 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 $[\sigma^{(1,2)}_{z}]$ . (g)-(i) Influence of $[\sigma^{(3)}_{x,y}]$ . (j)-(l) Influence of $[\sigma^{(3)}_z]$ . The symbols P1-P12 denote the sets of disorder parameters given in Table 1

. The QDs are assumed to be spherical.
