Research Abstract |
In this project we have performed the combinational photoemission spectroscopy using 3D soft x-ray angle-resolved, hard x-ray, and extremely low-energy photoemission in order to reveal the bulk electronic structure of strongly correlated electron systems. We have also developed a novel technique of photoemission called as polarization-dependent hard x-ray photoemission, by which the orbital distributions to the valence bands in solids can be detected. Actually we have found that the orbital symmetry of the conduction electrons are mutually and qualitatively different between gold and silver by using this technique.
