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.
