The dynamic theory of X-ray diffraction by the one-dimensional ideal superlattice. II. Calculation of structure factors for some superlattice models

The superlattice unit-cell structure factors are calculated for the trapeziform model, which may be used for the epitaxically prepared one-dimensional superlattice crystals if the interdiffusion is taken into account. The particular cases of this model are: (1) the rectangular model, which describes the superlattice if the interdiffusion is negligible; (2) the triangular model, which describes the superlattice if the interdiffusion takes place all over the layer thickness. The change of satellite intensities during the interdiffusion is discussed. The results obtained may be used to interpret the X-ray diffraction patterns produced by superlattices.
