摘要：

Metal-insulator transitions in 3d transition-metal oxides and sulphides including high-Tc superconductors have been studied by photoemission spectroscopy. The transitions result either from the closing of correlation gaps or from carrier doping. Strong electron correlation is found to result in highly non-rigid-band behaviors concerning the shifts of the Fermi level positions in the metallic region and complex changes in the spectral line shapes across the phase transitions. © 1990.
