摘　　要：扫描隧道显微镜或原子力显微镜使人们能够操纵吸附在材料表面的单个原子或分子.这种技术可从单个原子、分子开始组装具有特定功能的纳米结构,也能组装、拆解分子从而控制化学反应的进程,将在物理、化学等多学科领域发挥重要作用.本文综述了近年来在金属材料表面进行单原子操纵的研究进展,介绍了单原子操纵的方法和机制,并对有待进一步研究的若干问题进行初步探讨.Both the scanning tunneling microscope and the atomic force microscope enable the manipulation of single atoms and molecules on the surfaces. This technique makes it possible to fabricate nanostructures from single atoms and molecules and to control the chemical process by assembling and/or disassembling molecules, which will be important in many areas such as physics and chemistry. In this paper, we review the progress in the research of single-atom manipulation on metal surfaces. Different methods and mechanisms for the manipulation as well as some related issues are addressed. In addition, we discuss the problems which deserve further studies.
