Fourier energy analysis of Kikuchi patterns for investigation of defect system of diamond crystals

Abstract

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.
