| Research Abstract |
We newly developed an electrochemical frequency modulation atomic force microscope (EC-FM-AFM) for imaging on ionic-liquid(IL)/electrode interfaces. A quartz tuning fork sensor was used as a force sensor instead of a Si cantilever, which enabled atomic-resolution imaging even in viscous ionic liquid. In addition, the AFM system was installed in a vacuum chamber in order to reduce the effect of water. By using this AFM, reconstruction of ions on the IL/electrode interface was directly visualized.
