| Zusammenfassung: | We present results of electronic Raman-scattering experiments in differently doped YBa 2 Cu 3 O 6+x . In B 2g symmetry, an analysis of the data in terms of a memory function approach is presented and dynamical relaxation rates Γ (ω, T) and mass-enhancement factors 1 + λ(ω, T) for the carriers are obtained. Starting from temperatures T > 180K, Γ(ω, T) and 1 + λ(ω,T) are extrapolated to lower temperatures and used to re-calculate Raman spectra. By comparison with our data, we find a loss of spectral weight between T c < T < T* at all doping levels x. T* is comparable to the pseudogap temperature found in other experiments. Below T c , the superconducting gap is observed. It depends on x and scales with T c whereas the energy scale of the pseudogap remains the same. |
