摘要

We study the electronic structure of the LaMO3 (M = Ti-Ni) perovskite oxides as probed by various high-energy electron spectroscopics. These spectroscopic studies, in conjunction with model many-body calculations, provide important information concerning the ground state character of these oxides. In particular, the on-site Coulomb interaction strength, Udd, the charge transfer energy, Δ, and the transfer integral between the metal 3d and oxygen 2p states, t, have been estimated. These parameters are found to exhibit a systematic variation across the series. Electronic structure of the perovskites is discussed in terms of electron-removal and electron-addition spectra for the parent compound as well as for doped LaMO3, with specific reference to semiconductor-metal transitions.
