在本文的工作中，我们利用低温扫描隧道显微镜（LT-STM）系统对单个原子进行了精确的操纵。我们展示了如何使用LT-STM成像和修饰大块Ag（111）表面，并操纵来自衬底的Ag原子和Ag（111）衬底上的蒸发吸附物。我们提出了一个协同组合STM诱导的修改和有序阵列的纳米级结构。特别地，我们证明了在Ag（111）衬底上修饰Ag原子纳米结构的能力，并且来自衬底的单个Ag原子和蒸发的吸附物可以在Ag（111）衬底上书写一些英文字母和汉字。通过这种方式，我们提供了一个有效的基础来探索纳米结构的基本物理特性，并以“自下而上”的方法开发纳米技术。
In the work reported in this paper, we have used a low-temperature scanning tunnelling microscope (LT-STM) system to manipulate accurately single atoms. We show how we can use a LT-STM to image and modify a bulk Ag(111) surface and manipulate Ag atoms from substrate and evaporated adsorbates on Ag(111) substrates. We present a synergistic combination of STM-induced modification and ordered arrays of nanometre-scale structures. In particular, we demonstrate the ability to modify Ag atomic nanometre structures on the Ag(111) substrate and some English letters and a Chinese character can be written by single Ag atoms coming from the substrate and evaporated adsorbates on Ag(111). In this way, we supply an effective basis to explore the fundamental physical properties of a nanometre structure and to develop nanotechnology with a `bottom-up' approach.
