摘要：

The electronic structure of the high temperature superconductors, YBa2-Cu3O7-x and Bi2Sr2CaCu2O8 have been studied by high energy electron energy-loss spectroscopy in transmission mode. We could derive the dielectric functions from the low energy loss spectra below ∼ 40eV. These dielectric functions give information on plasmons, interband transitions and low-lying core levels. From the core electron excitation spectra, we obtain information on the unoccupied electronic states. © 1990 IOP Publishing Ltd.
