(a) GISAXS pattern from a composite thin film of self-assembled Au nanoparticle–CTAB micelles in the presence of silica precursors. The diffraction peaks are calculated using either a primitive rhombohedral unit cell ([R\overline{3}m]) or a face-centered cubic unit cell ([F\overline{4}3m]), with their corresponding diffraction plane indices labeled on the left and right sides of the GISAXS pattern, respectively. {} means the equivalence of h, k and l. The reflection and transmission channels merge because the incident angle is chosen exactly at the critical angle. For clarity, only one channel is displayed. View (b) illustrates the equivalence of the two lattice interpretations. For both, the [111] direction is normal to the surface.
