| Outline of Final Research Achievements |
In order to investigate friction phenomena on nanoscale, atomic force microscopy (AFM) was combined with electron microscopy. The true and mirror images of the AFM cantilever tip apex (as a object) are appeared and overlapped with the reflection electron microscopy image of a sample surface (as another object). This technique enale us to detect the tip-surface force together with atomic-scale structure images of two objects around the gap.
Using the developed bimodal atomic force microscopy, the tip-surface force components were first expressed as vectors, providing the vector distribution above the surface at the subatomic scale. The bimodal AFM approach will allow researchers to investigate the physical properties of materials in greater detail on the nanoscale, nanotechnology, and friction/lubrication systems.
