Dislocations in single-crystal silicon created by the four-point bending method are investigated using a laboratory X-ray source. Two- and three-dimensional diffraction images in the Laue geometry of unusual X‑shaped dislocation structures have bee

The brownmillerite phase has been studied by X-ray diffraction and Mossbauer methods. The available data on single-phase compounds with the perovskite structure in strontium ferrite SrFeO3 – δ are analyzed. All the valence states of iron for any p

The features of forming section and projection topography images of an edge dislocation normal to the crystal surface are considered for the case of X-ray anomalous transmission. Experimental images are analyzed using numerical simulation of the diff

This paper is a continuation of previous studies on the development of X-ray topo-tomography using laboratory equipment. The results on the spatial location of a single polygonal dislocation half-loop in a silicon single crystal were obtained as a re

X-ray topography is a set of X-ray diffraction techniques that make it possible to see images of defects, to determine their type and location in the volume of the crystal structure or on its surface, and to measure their main characteristics. The re

A new high-sensitivity X-ray diffraction technique for studying local surface deformations caused by crystal defects is described. The method is based on analysis of the shape of “bending interference fringes” (BIFs) in the Bragg geometry of X-ra

We present the results of experimental and theoretical studies of generation of terahertz radiation during reflection of a femtosecond-long laser pulse from a metal surface. It is shown that a greater part of the experimental results (narrow directiv

The features of terahertz radiation generated upon oblique incidence of a femtosecond laser pulse on a metal surface are investigated theoretically. We propose a Cherenkov-type generation mechanism associated with excitation of low-frequency surface
