大气状态下STM电场加工机理分析

Analysis on Electric-field-fabrication with STM in Air

扫描探针显微镜 (SPM)家族的拓展始于扫描隧道显微镜 (STM) ,它的发明使人类能够真正获得物质表面在原子尺度上的局域电子结构 ,并可揭示与之对应的原子结构。基于 SPM的纳米加工技术同样是从 STM开始的 ,本文主要介绍大气状态下 STM在 Au和 Ti表面的电场加工结果 ,并对其作用机理进行较深入分析 。

The family of Scanning Probe Microscope (SPM) expands from Scanning Tunneling Microscope (STM),the invention of which makes it possible for people to get local area electric structures in atomic size on the surface of certain materials,so as to illustrate correspondence atomic structure.Nano-fabrication based on SPM also begins from STM.So in this paper, we discuss the results of the electric-field-fabrication with STM on Au and Ti in air,the functional theory of which is analyzed deeply and decided to be the combination of mechanical contact and electric-field-induced oxidation.
