| Outline of Final Research Achievements |
Visualization and control of atomic and molecular motions in the nanometer scale has been very difficult because the dynamics associated with the nanoscale is in the range of picoseconds or femtoseconds. To investigate such a ultrafast timescale in the nanoscale, we combined the scanning tunneling microscope with the terahertz spectroscopy. As a result, we succeeded in observing the picosecond and femtosecond electron tunneling in the nanogap and the photoincuced phase change at the nanoscale. These results could be very useful for the future nano-electric devices.
