An area observed with a transmission electron microscope (TEM) was illuminated with a far-field light probe (with a diameter of 10 μm) under the TEM observation. A tungsten tip covered with a silver layer (with a diameter of 60nm at the tip apex) was placed close to the observed area, and an intense near-field light was induced in the immediate vicinity of the tip apex due to a tip-enhanced effect. By using the near-field light probe with a high spatial resolution beyond the diffraction limit of light, photo-induced glide of an individual dislocation was demonstrated in ZnO.
