锗单品的位错研究

摘要

The dislocation of germanium single crystal was studied by metallographic examination method.The test indicate that the exhibition of the dislocation would be affected by corrosive agents.The exhibition of the dislocation was clear when the crystal was corroded by the potassium ferricyanide cor rosive agents.Shape of dislocation corrosive pit was triangle,The dislocation desity was 11 339root/cm2 by calculation.%采用金相分析方法研究了锗单晶的位错，腐蚀试剂的选择对位错的显示有较大影响。实验表明，铁氰化钾腐蚀液能清晰地显示出锗单晶的位错，其位错腐蚀坑的形状是三角形，经过计算，锗单晶的位错密度大约为11 339根／cm2。
