电化学扫描探针显微术是将电化学研究系统和扫描探针显微技术 (ScanningProbemi croscopy :SPM)相结合而产生的一门新的研究技术 ,是对SPM技术的创新和应用领域的拓展。该技术的最大特点是可以在溶液环境下工作 ,实时、原位、三维空间观察、控制化学反应及过程 ,又可以对材料进行原子级加工等。本文将以SPM技术的重要分支———电化学扫描隧道显微技术 (STM :Scanningtunnelingmicroscopy)为主 ,简要介绍其工作原理 ,应用范围及发展趋势。 Electrochemical Scanning Probe Microscopy is a new research technique that combines the electrochemical research system and Scanning Probe Microscopy (SPM). It is an extension of the innovation and application of SPM technology . The most important feature of this technology is that it can work under solution environment, observe in real time, in situ and three-dimensional space, control chemical reactions and processes, and can also process materials at atomic level. This article will be an important branch of SPM technology - electrochemical scanning tunneling microscopy (STM: Scanningtunnelingmicroscopy) mainly introduces its working principle, application scope and development trend.
