概 要 | Joint seminar of Fritz Haber Institute and Institute for Molecular Science, Japan
Photoelectron micro-spectroscopy and spectro-microscopy are important approaches for elucidating the local electronic properties of micro- and nano-structures. By combining the photoelectron momentum microscope (PMM) and a soft X-ray synchrotron radiation, three-dimensional momentum-resolved photoelectron spectroscopy with a microscopic field of view is realized. We have built a new PMM station at the soft X-ray beamline BL6U of UVSOR. With a photon energy range up to 800 eV covered by the BL6U, core-level excitation of a variety of important elements including C, N, O and transition metals is possible. Specific atomic sites and electronic states can be selectively characterized by the spectator and participant Auger processes, respectively. Resonant momentum-resolved photoelectron spectroscopy is yet a challenging field that opens the door to elemental- and orbital-selective valence band dispersion analysis.
