金刚石型结构晶面间距及结构因子的计算

Calculation of Interplanar Spacing and Structure-Factor of Diamond-Type Structure

用添加原子的“位置因子S”,得到了金刚石型结构可能的四种面间距。计算了这种结构的结构因子,并分析了晶面间距与结构因子的相关性。讨论了金刚石型结构与面心立方结构间消光条件的差异。

With the “site-factor S” of an addition atom, the possible four kinds of interplanar spacing of diamond-type structure was calculated. In addition, the structure-factor of this structure was calculated, and a correlativity between the interplanar spacing and the structure-factor was analysed. Finally, a difference in missing reflection conditions between diamond-type structure and face-centered cubic structure was discussed.
