3. Photoemission Studies of the M/Si(111)-3x1 Reconstructions for M=Li, Na, K, and Ag
Abstract : The work reported here relates to a class of reconstructions on the Si(111) surface with 3?1 or 6?1 periodicity that are believed to be similar for Ag, Mg and the alkali metals (Li, K, and Na). The electronic structure of this reconstruction was studied by means of angle-resolved photoelectron spectroscopy of the valence bands of the Ag/Si(111)-3?1/6?1 reconstruction. READ MORE

5. Photoelectron Spectroscopy of Cuprates and Manganites
Abstract : Abstract In this thesis, the high temperature superconductors (HTSC) La2CuO4+x and Bi2Sr2CaCu2O8+d and the colossal magnetoresistive (CMR) La1-xSrxMnO3 have been studied by photoelectron spectroscopy. Techniques such as angular resolved photoemission (ARPES), resonant photoemission spectroscopy (RESPES) and x-ray absorption spectroscopy have been applied, using synchrotron radiation. READ MORE
