| Outline of Final Research Achievements |
To investigate electronic structure of materials is important for understanding the physical properties. The electronic state below the Fermi level can be observed with high energy resolution and momentum dispersion curve by angle-resolved photoelectron spectroscopy (ARPES). The state above the Fermi level, on the other hand, can be detected by angle-resolved inverse photoelectron spectroscopy (ARiPES), but with low energy resolution. Here, we developed a new-type ARiPES instrument with a high brilliant electron source, which was firstly installed for solid-state physics, and a vacuum-ultraviolet spectrometer with a X-ray CCD.
