Superconductivity-induced changes of the phonon resonances in RBa_2Cu_3O_7 (R=rare earth)
S. Ostertun, J. Kiltz, A. Bock +2
We observe a characteristic energy eV which separates regions of different behavior of the phonon intensities in the Raman spectra of the …
Electron-Phonon Coupling Deduced from Phonon Line Shapes
A. Bock, S. Ostertun, K. -O. Subke
We investigate the Fano-type line shape of the Ba mode of Y_{1-x}Ca_xBa_2Cu_3O_{6+y} films observed in Raman spectra with A_1g symmetry. The line shape is described with an extende…
Anomalous Self-Energy Effects of the B_1g Phonon in Y_{1-x}(Pr,Ca)_xBa_2Cu_3O_7 Films
A. Bock, S. Ostertun, R. Das Sharma +2
In Raman spectra of cuprate superconductors the gap shows up both directly, via a redistribution of the electronic background, the so-called "2Delta peaks", and indirectly, e.g. vi…
Resonant Raman Study of Superconducting Gap and Electron-Phonon Coupling in YbBa2Cu3O7-delta
S. Ostertun, J. Kiltz, T. Wolf +1
We investigate the electronic background as well as the O2-O3 mode at 330 cm^-1 of highly doped YbBa2Cu3O7-delta in B1g symmetry. Above the critical temperature Tc the spectra cons…
