Photoelectron Spectroscopy of High Temperature Superconductors and Related Compounds
In this thesis, the high temperature superconductors (HTSC) Ba0.6K0.4BiO3, La2CuO4+x, Bi2Sr2Ca1-xYxCu2O 8+d, Bi2Sr2CuO6+d as well as semiconducting Ba0.9K0.1BiO3 and the strongly magnetoresistant material La1-xSrxMnO3 have been studied by photoelectron spectroscopy. By using the tunability of synchrotron radiation, techniques such as resonant photoemission and x-ray absorption spectroscopy have be
