The defect structure of p-CdTe:Cl single crystals and MoOx/p-CdTe/MoOx heterostructures based on them were investigated by high-resolution X-ray diffractometry methods. Different models of dislocation systems were applied, according to which the densities of dislocations were estimated from the Wilson-Hall plot. It is shown that the application of the MoOx layer significantly affects the density of dislocations and their influence on the electrical and spectroscopic properties of heterostructures is estimated
Crystal and magnetic domain structures of iron garnet films with different thicknesses are studied by means of atomic and magnetic force scanning microscopies as well as by means of high-resolution Х-ray diffraction. The model of the garnet films as a set of vertical columns with certain lateral sizes is proposed and substantiated. Within this model, X-ray intensity distributions in the vicinity of the reciprocal lattice points are calculated using the Monte Carlo approach to determine densities of two dislocation types with different Burgers vectors.
Values of average deformations in local regions of synthesized diamonds are determined using the power Fourier spectrum in the analysis of Kikuchi pattern. The degree of bands blurring on image is related with the deformation, which are quantitatively described through the changes of average radial period of the energy spectrum. The planar distribution of deformations is allowed to determine anisotropy by the magnitude and direction in the crystal.
