Simulated small-angle structure factor
S(q) for (a) lamellar, (b) cylindrical and (c) b.c.c. spherical mesophases. Three methods are used to compute
S(q): with s on a cubic lattice (green vertical lines), with s on spheres (blue dotted line) and Debye's scattering equation (red solid line). The Debye result for
S(q) of a homogeneous glass, after being vertically rescaled to align at , is shown for comparison (black dashed line). Black downward-pointing arrows mark signature peaks for each structure. The broad peak at corresponds to particle size σ. Insets show top/side views of the configurations under consideration. The blue solid line in (c) is the Debye result for
S(q) of a b.c.c. sphere mesophase with one particle per domain, obtained by rescaling the curve of a b.c.c. crystal. |
