Times Cited Count：5 Percentile：26.70(Spectroscopy)The effect of laser annealing on electronic atructures and molecular orientation for poly(dimethylsilane), {PDMS, [Si(CH
)
]
} has been studied by synchrotron radiation photoemission and photoabsorption spectroscopy. Prior to annealing, PDMS powder was mounted on the basal plane of highly oriented pyrolytic graphite. Both Si 1s X-ray photoemission spectroscopy and near-edge X-ray absorption fine structure (NEXAFS) spectroscopy at Si 1s edge show that electronic structures have been modified due to annealing. Furthermore, the angle-dependent NEXAFS spectra clearly indicate that the annealed products maintain a specific orientation. Interestingly, no such kind of orientation is present in as-received PDMS powder as no angle-dependency is observed before annealing.

Times Cited Count：1 Percentile：5.54(Spectroscopy)Current research in the perovskite and layered perovskite-type manganese oxides has expanded to include the study of electronic and magnetic properties such as the colossal magnetoresistance (CMR), orbital ordering and charge ordering. The O K soft X-ray emission and absorption spectra (XES and XAS) of LaSrMnO were measured at selected excitation energies in order to investigate the electronic structure. The measurements were carried out by using a soft X-ray emission spectrometer at beamline BW3 at HASYLAB, Germany. The dependence of O K XES on excitation-energy was observed. It is attributed the different site of oxygen ions.

Times Cited Count：7 Percentile：31.13(Physics, Applied)Carbon films on Japanese smoked roof tile "Ibushi-Kawara" were characterized by high-resolution soft X-ray spectroscopy using synchrotron radiation. By comparing the soft X-ray emission and absorption spectra of Kawara with the reference carbon compounds, it was determined that the carbon films on Kawara consist of mostly carbon-black-like sp2 carbon atoms and that the surface also contains polyethylene-like sp3 carbon atoms. The take-off/incident-angle dependence on the X-ray emission/absorption spectra of Kawara implies that the carbon-black-like sp2 carbon atoms partially form a layer structure parallel to the basal clay plane. From the take-off-angle dependence of the p/s-peak intensity ratio in the X-ray emission spectra, the layer ordering of the carbon films is estimated to be 50% of highly oriented pyrolytic graphite (HOPG). Therefore, the metallic oxidized color and durability are due to the layer structure and the random structure that connects the layer-structured clusters, respectively.
