摘要：
In strongly correlated electron systems electron-electron interactions lead to the formation of the density of states peaks and to enhanced scattering at certain energies in the vicinity of the Fermi level EF. These sharp features are pinned with respect to EF, if proper conditions are fulfilled. The pinning makes it possible to reproduce the systematic variation of temperature dependences of resistivity, the Seebeck coefficient S(T), Hall concentration and magnetic susceptibility, caused by the change of composition on the metallic side of the metal-insulator transition in La2-xSrxCuO4 and other high-Tc oxides. © 1990.
