用扫描隧道显微镜（STM）研究了Si(111)7×7表面原子台阶下台阶的终止。提出了相对于下层露台末端7×7单元网格的7个台阶位置，其中10个已经在STM图像中观察到。提出了在步骤处终止的规则。描述了步骤的结构和重组
The termination of the lower terrace at the atomic steps on the Si(111)7×7 surface has been investigated with scanning tunneling microscopy (STM). It is proposed that seven positions of the steps relative to a 7×7 unit mesh of the end of the lower terrace are possible for each of two step directions, and ten of them have been observed in STM images. A rule for the termination at the steps is proposed. Structure and restructuring of the steps are described
