X-ray section images of dislocations and dislocation barriers in Si

摘要

By means of numerical solution of the Takagi equations, modeling of X-ray topographic images of deformation fields of the Lomer-Cottrell dislocation loops and dislocation barriers is made depending on their spatial location for the thin and thickrncrystals. Diffraction images created by dislocation loops and barriers of different size and spatial location are complicated and versatile in their thin structure.
