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.

用于金刚石晶体缺陷系统研究的菊池图的傅里叶能量分析
在菊池图案分析中,利用功率傅立叶谱确定了合成金刚石局部区域的平均变形值。图像上波段模糊的程度与变形有关,可以通过能谱平均径向周期的变化来定量描述。变形的平面分布可以通过晶体的大小和方向来确定各向异性。
