| Outline of Final Research Achievements |
On the well defined surfaces of solids, we tried to make organic ultra thin films with film thickness at around one molecular layer. By focusing unoccupied states of molecules, we have measured electronic structures ranging from nanometer to macroscopic scale, by using two-photon photoemission(2PPE) spectroscopy and scanning tunneling microscope (STM). By using STM and STM-based local spectroscopy, we can investigate the electronic states as well as superstructures, which enables us to understand the one-to-one correspondence between them. In particular, by focusing on the unoccupied surface image potential states, we can understand the formation of electronic band structures starting from single molecules. Furthermore,localized or delocalized nature of electronic states is understood from the viewpoint of atoms and molecules.
