利用原子分辨率的非接触原子力显微镜(NC-AFM)对B/Si(111)<$3 × <$3表面进行了观察。在AFM图像中出现两种类型的斑点(暗点和亮点)。暗点对应于其中次表面原子是B原子的BS 5结构,而亮点对应于其中次表面原子是Si原子的Si-T 4结构。通过NC-AFM,我们成功地确定了表面下的原子种类之间的差异,如Si和B原子。
We observe the B/Si (111)√ 3×√ 3 surface by noncontact atomic force microscopy (NC-AFM) with atomic resolution. Two types of spot (dim and bright spots) appear in AFM images. The dim spots correspond to the BS 5 structure where the subsurface atom is the B atom, while the bright spots correspond to the Si-T 4 structure where the sub-surface atom is the Si atom. By NC-AFM, we successfully determine the difference between the atom species under the surface, such as Si and B atoms.
