Figure 4
Two-dimensional patterns of the IGIXS(q) profile, which were calculated with varying rotation matrix R values. In these calculations, we fixed several parameters: d3 = 2.0 nm, g33 = 0.09, g3r = 0.05, dr = 0.8 nm, gr3 = 0.15, grr = 0.15, β = 90° and αi = 0.20°. (a) Pattern for thin films which assumed that the n vector in the film is perfectly oriented normal to the film plane (see the model in the inset); (b) the n vector lies perfectly parallel to the film plane (model shown in inset); (c) the n vector is randomly oriented within the film (model shown in inset); (d) the n vector has a distribution which follows a Gaussian function ([\overline \varphi] = 0° and σφ = 15° in equation 12[link]) (model shown in inset).
