|Outline of Final Research Achievements
In this study, we have improved the speed of three-dimensional scanning force microscopy (3D-SFM) imaging of an atomic-scale 3D hydration structure from 1 min/image to 3 s/image. In addition, we added closed cell and fluid-exchange function to the 3D-SFM system. With this improved setup, we performed imaging of various molecular adsorption structures. For example, we imaged methanol adsorption structures on a graphite surface in a volatile methanol-water mixture. We also imaged adsorption structures of surfactants (CTAB) and their concentration dependence was investigated by the fluid exchange system. These results demonstrate that usability and effectiveness of the developed 3D-SFM system for 3D molecular adsorption structure analysis.
