| Outline of Final Research Achievements |
In this project, we aimed to develop an experimental technique that enables us to detect vibrational excitation and relaxation dynamics of surface reaction coordinate with characterizing adsorbate adsorption states. We have constructed a ultra-low temperature scanning tunneling microscopy with a laser irradiation system onto the scanning tip. We successfully observed the flip motion of hydroxyl radicals induced by femtosecond laser irradiation. We further investigated plasmonic response of a single atomic layer of alkali atoms and found that the response is largely enhanced by interaction with two-dimensional materials.
