Optical spectra of YBa2Cu3O7 monocrystalline films on Li2B4O7 (001) substrates in the 0.2-6 eV spectral range

  • 1. Franko Lvov State Univ. (Ukraine)

Description

Studies of YBa2Cu3O7 films on Li2B4O7 substrates showed that the excitation energy of plasmons related to free carriers is weakly anisotropic in the ab plane. The corresponding splitting (0.16 eV) is far less than that in crystals (≅0.58 eV). The splitting of plasmons related to the valence electrons lies within 0.05-0.10 eV. The plasmon energies in films and in crystals are shifted by 0.5 eV. 8 refs., 2 figs
