| 英文摘要 | The valence band evolution Of C-60 film upon Yb intercalation is investigated by the synchrotron radiation photoemission spectroscopy (SR-PES) technique. The results show that only Yb2.75C60 forms at lower intercalation stages and imply that other phases of YbxC60 (x > 2.75) form with more Yb atoms intercalated into the Yb2.75C60 sample. No Fermi edge is observed for all the spectral lines in this work, which reveals that the superconducting Yb fulleride, whether it is Yb2.75C60 or other phase, has semiconducting property at room temperature. To extract the intrinsic density of state of the valence band from the Yb 4f-superposed experimental data, the SR-PE spectra were measured for the well-defined phase of Yb2,75C60 with varying photon energies (18.0-45.0 eV). The results show that the spectral data can drastically depart from the density of states of the valence band due to the photoemission of Yb 4f core levels. However, the valence band can, still be quantitatively extracted from the experimental data by the least-square simulation. |
