| 摘 要： | 面心立方晶体中层错矢量为1/6<112>和1/3<111>的堆垛层错在生长面{111}上的露头处产生了亚台阶(sub-step)。基于亚台阶的原子图象的分析,本文讨论了层错生长机制及其生长动力学,证明了亚台阶处的成核势垒总是小于二维成核势垒,解释了近年来所观察到的堆垛层错作为生长台阶源的实验事实。

| Abstract: | The atomic configurations of sub-steps created on (111) growth surface of fee crystal by stacking faults with fault vectors 1/6〈112〉and 1/3〈111〉show that they can act as growth step sources. Growth kinetics of stacking fault growth mechanism has been analysed. It has been shown that the nucleation barrier at the sub-steps is always smaller than that of the 2-di-mensional nucleation. |
