Progress of surface and interface science using synchrotron radiation in Japan is reviewed. Investigations for electronic structure, atomic structures including magnetic, catalytic, other functional origins with dynamical information have been done. Historical milestones future prospects are discussed.

Abstract We demonstrate that the modulated surface photovoltage spectroscopy (modulated SPS) technique can be applied to investigate interface states in bandgap, i.e. passivation, of crystalline silicon coated with a downshift layer such as hydrogenated aluminum nitride embedded terbium ions by suppressing straylight cut-off filter. Different hydrogen contents influence spectra at photon energi...
