| Research Abstract |
The aim of research is to build up periodic superstructures made of polarized medium on surfaces, and to investigate the electron solvation dynamics in femtosecond time scale. The second aim is to observe the superstructures from atomic and molecular point of view. In addition to microscopy, scanning probe spectroscopy is applied to measure the electronic states of superstructures. In distance-voltage measurements on naphthalene thin film formed on HOPG substrate, some unoccupied levels and image potential states are observed for specific superstructures. These trends are completely in agreement with that of detected by 2PPE and we can discuss the correlation between macro and nano scale for microscopic/spectroscopic measurements.
