Grazing-incidence X-ray scattering (GIXS) formulas for hexagonally perforated layer (HPL) structures withABCandABstacking sequences were derived, and used in the quantitative analysis of the two-dimensional GIXS patterns of polystyrene-b-polyisoprene (PS-b-PI) diblock copolymer thin films supported on silicon substrates. This quantitative analysis provided detailed information (shape, size and size distribution, packing order, layer packing sequence, and orientation) about the HPL structure of the diblock copolymer films that cannot be easily obtained with conventional X-ray and neutron scattering techniques or with conventional microscopic methods.

In this study, a grazing-incidence X-ray scattering (GIXS) formula was derived for gyroid structures formed in thin films supported on substrates. Two-dimensional GIXS patterns were measured for gyroid structures formed in polystyrene-b-polyisoprene (PS-b-PI) diblock copolymer nanometre-scale thin films supported on silicon substrates, and a quantitative analysis of the obtained two-dimensional GIXS data was conducted with the scattering formula. This analysis provided details (lattice parameter, width of the PS phase, positional distortion factor, orientation and orientation distribution) of the gyroid structures developed in the diblock copolymer thin films that are not easily obtained using conventional techniques. Moreover, it was possible to simulate complete and detailed two-dimensional GIXS patterns with the determined structure parameters.

Recently, surface and thin-film studies using area detectors have become prevalent. An important class of such systems are lamellar thin films formed by small molecules, liquid crystals or semicrystalline polymers. Frequently, the lamellae align more or less parallel to the substrate. Such structures can be easily discerned by their characteristic X-ray scattering close to the incident plane. This paper describes how such patterns can be simulated, in order to extract morphological information about the thin film.
