Outline of Final Research Achievements

We investigated the method for measuring the optical near-field using photon-induced force detection with high sensitivity and high spatial resolution. We also investigated the mechanism of the atomic resolution imaging. We demonstrated atomic resolution imaging of the near field on the α-Al2O3 (0001) surface of a prism. We invstigated the spatial distribution of the near field by scanning at different tip-sample distances and found that the atomic corrugation of the near-field signal was observed at greater distances than that of the atomic force microscopy signal. We clarified that the Al atoms on the α-Al2O3 (0001) surface were resolved at an atomic level.
