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

利用低温STM和STS研究了Fe和Co原子及其团簇在Pt（111）表面的激发。从硬X射线和软X射线以及低于10 eV的组合光电子能谱，体和表面电子结构之间的差异被澄清。在LiV_2O_4中，在价带谱中观察到反冲效应。同时，半定量地讨论了ELEPES的体/表面灵敏度。最后讨论了用Fe-O自旋探测器研究高效率自旋极化光电子和用动量显微镜进行二维kx-ky带的全谱。

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.
