Development of a New Electrochemical Atomic Force Microscopy Tool for Obtaining Surface Morphology Through Electrochemical Reaction

초록

Electrochemical atomic force microscopy is a complex electrochemical analysis method that has been applied in many fields. Electrochemical atomic force microscopy consists of an electrochemical cell, electrochemical analysis system, and atomic force microscopy. To simultaneously analyze the electrochemical system and the atomic force microscopy, an electrochemical cell with a suitable structure is needed. We developed the electrochemical atomic force microscopy analysis system using a self-developed electrochemical cell. To confirm the in-situ analytical ability of the developed electrochemical atomic force microscopy analysis system, we observed the electrochemical corrosion process of copper with respect to changes in pH of a sulfuric acid solution. The operation of the electrochemical atomic force microscopy tool was verified by experiments on the electrochemical corrosion of copper, and the factors affecting the corrosion process were examined. It was confirmed that electrochemical atomic force microscopy can perform electrochemical analysis and atomic force microscopy image analysis at the same time.
