| Outline of Final Research Achievements |
In recent years, it has become important to form transistors using quantum nanostructures such as nanowires and molecules, and to apply electron dynamics in these structures to open up a new dimension in electronics. However, the interaction between terahertz (THz) electromagnetic waves, which are very effective in elucidating and controlling the properties of nanostructures, and ultrafine nanoscale quantum structures is extremely weak.
In this study, we focused THz electromagnetic waves far beyond the diffraction limit by using an ultrasmall metal electrode with a gap of nm order as an antenna for THz waves, and clarified the electronic states and transport dynamics in ultrasmall nanostructures.
