扫描隧道显微镜问世于８０年代初，并以前所未有的直观性揭示了研究多年而未获答案的Ｓｉ（１１１）７×７表面结构，从而引起了包括表面科学家在内的科技界的极大兴趣。在此之前，用于表面科学研究的方法虽不计其数，但能像扫描隧道显微镜那样可给出表面的原子分辨实空间像，能对表面作局域、动态、多功能研究，甚至可以兼作表面制备的方法却几乎没有．文章通过我们近年来研究中的一些实例说明了扫描隧道显微镜对表面科学的巨大推动。
Scanning tunneling microscopy was first introduced in the early 1980s and revealed the unrecognized Si (111) 7 × 7 surface structure for many years with unprecedented intuition, attracting great interest from the scientific community, including surface scientists. Prior to this, although there are numerous methods for surface science research, they can provide surface-like atomic resolution of real-space images like scanning tunneling microscopy and can perform localized, dynamic, multi-functional studies on the surface and can even double as Surface preparation methods are almost no. The article illustrates the great promotion of surface science by scanning tunneling microscopy through some examples in our recent studies.
