Outline of Final Research Achievements |
Frequency-modulation atomic force microscopy (FM-AFM) provides a promising tool to observe the solid topography and also liquid structure at liquid-solid interfaces. The cantilever with a tip is mechanically oscillated. Force pushing or pulling the tip shifts the resonance frequency of the oscillation. Microscopes with force sensitivity of 10 pN or better in water have been developed and commercialized to date. In this study, two-dimensional frequency-shift distributions observed at interfaces including water-calcite were interpreted with Gibbs free energy distribution perturbed by solid surfaces.
