本文介绍了用低温扫描隧道显微镜对金属表面单原子和单分子进行可控横向操纵的实验。低温STM，它在15和300 K之间的温度范围内工作，和实验方面的重要操作的设计进行了讨论。在介绍了横向操纵的基本原理后，表明单个原子/分子可以用尖端推拉。除了操纵吸附种，还可以从扭结的位置和台阶边缘提取衬底原子。一个完整的一系列的操纵过程与基板原子，这允许一个原子的金属表面的原子重组，示出。
The controlled lateral manipulation of single atoms and molecules on a metal surface with a low temperature scanning tunneling microscope is presented. The design of the low-temperature STM, which operates in the temperature range between 15 and 300 K, and experimental aspects important for manipulation are discussed. After an introduction to the basic principles of lateral manipulation it is shown that single atoms/molecules can be pushed and pulled with the tip. Apart from the manipulation of adspecies it is also possible to extract substrate atoms out of kink s sites and from step edges. A complete series of manipulation processes with substrate atoms, which permit an atom-by-atom restructuring of a metal surface, is shown.
