扫描隧道显微镜单原子操纵技术及其物理机理

扫描隧道显微镜不仅使得人们的视野可以直接观察到物质表面上的原子及其结构,并进而分析物质表面的物理性质,它还使得人们可以在纳米尺度上对材料表面进行各种加工处理,甚至可以操作单个原子,这一特定的应用将会使人类从目前微米尺度的加工技术迅速跨入纳米尺度和原子尺度。这将是推动人类科学和技术发展的一个无法估量和替代的动力。文中介绍近年来这一前沿研究领域所取得的部分进展,并讨论原子操纵的物理机理和应用前景。

STM Single AtomManipulation Technology and Its Physical Mechanism

The scanning tunneling microscope(STM), which was invented for imaging the topographic and electronic structures of solid surfaces at the atomic level, is becoming a promising method for manipulating single atoms and fabricating nanometer scale structures on solid surfaces. This capability makes it increasingly attractive and powerful for use in diverse areas of science and technology. This article introduced some new approach of single atom manipulation with STM and discussed the involved physical mechanisms.
