| Outline of Final Research Achievements |
In this study, we evaluated the mini-band structure of superlattice structure with the visible-light photoemission spectroscopy developed by us. In addition, the energy distribution of the conducting electrons in the mini-band was measured, too. In particular, the exciting-light-energy dependence of the electron distribution was investigated. As a result, we successfully measured the energy of electrons conducting in the second mini-band. This means that the part of the electrons in the second mini-band reached to the surface without its relaxing to the first mini-band.
