| Outline of Final Research Achievements |
We were aiming to develop a new vibration-free dynamic mode AFM system based on Fano resonance in the vibration spectrum of an optically driven AFM cantilever. For this purpose, we studied the mechanism and controllability of Fano resonance in the vibration spectra of a cantilever, and developed a scattering-type near-field optical microscope to measure plasmonic local fields with high sensitivity and high spatial resolution. As a result, we found that the vibration spectrum exhibits Fano resonance and the asymmetry of the resonance curve strongly depends on the position of the excitation spot along the central axis of the cantilever. From our simple analytical model, we attributeed this phenomenon to the interference between resonance and continuous components. Furthermore, we also find that the cantilever vibration is strongly suppressed with a phase gradient of 0.210 rad/Hz at resonance when the excitation-spot position is 61 um from the free end of the cantilever.
