| Outline of Final Research Achievements |
This study has been aimed at the realization of angle-resolved photoelectron spectroscopy (ARPES) and absorption spectroscopy (XAS) measurements by utilizing linear/circularly polarized microfocus VUVSX synchrotron light at AichiSR and the exploration of novel topological-materials. For the former, the polarization-dependent VUVSX synchrotron radiation imaging spectroscopy system in Aichi SR is limited for fixed photon energy, owing to the beam instability as remaining issue. For the latter, we found the existence of spin-polarization tangential to the Fermi surface with Rashba-type spin-splitting on the layered MAX phase compound V2AlC and the existence of unique helicoid electronic states on the cubic chiral compound NiSbS.
