| Research Abstract |
In this project, we proposed to excite plasmons by the electron injection and to visualize the plasmon wavefunctions by a scanning tunneling electron microscope. We developed the microscope based on the scanning near-field optical microscope. The microsope can achieve a spatial resolution less than a few tens nm in topography, optical, and tunnel electron images. We found that a characteristic spatial feature was visualized in the tunnel electron image for the gold thin film. Alternatively, we visualize plasmon wavefunctions excited in various nanostructures by using the scanning near-field optical microscope.
