Abstract

The structure of a powder germanium treated in a planetary mill in the presence of small (5–25%) additions of diamond powder has been studied by high-resolution transmission electron microscopy using a JEM-2010 electron microscope. As a result of the treatment, twins and stacking faults have been detected in germanium along plane (111). The germanium deformation is shown to lead to the polytypism. The studies show the existence of phase 9R with the following sequence of lay6ers: …BABCBCACA…. Some particles demonstrate the partial or complete GeI → GeIV and GeI → GeIII phase transitions.

行星磨中处理过的锗的结构

摘要

通过使用JEM-2010电子显微镜的高分辨率透射电子显微镜研究了在少量（5–25％）金刚石粉添加的情况下在行星式磨机中处理过的锗粉的结构。处理的结果是，沿着平面（111）在锗中检测到孪晶和堆垛层错。显示出锗变形导致多型性。研究表明存在9 R相，并按以下顺序排列：…BABCBCACA…。一些粒子显示出部分或完全的GeI→GeIV和GeI→GeIII相变。
