Electron Spectroscopy of Strongly Correlated Systems from 10meV up to 10keV

用低温STM和STS方法研究了Fe、Co原子和团簇在铂(111)表面的激发。在硬X射线、软X射线以及10 eV以下的联合光电子能谱中，阐明了体电子结构和表面电子结构的差异。在LiV2O4中，在价带光谱中观察到了反冲效应。同时，对ELEPES的体/表面灵敏度进行了半定量的讨论。最后讨论了用Fe-O自旋探测器进行高效自旋极化光电子研究和用动量显微镜绘制完整的二维kx-Ky带图。

By means of low temperature STM and STS, excitations of Fe and Co atoms and clusters on a Pt(111) surface were studied. From combined photoelectron spectroscopies in the hard and soft X-rays as well as below 10 eV,differences between bulk and surface electronic structures were clarified.In LiV2O4, the recoil effects were observed in the valence band spectra. Meanwhile, the bulk/surface sensitivity of ELEPES was semiquantitatively discussed. Finaly, high efficiency spin-polarized photoelectron study by use of a Fe-O spin detector and a complete two dimensional kx-ky band mapping by a momentum microscope were discussed.
