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 …
Electronic Raman Scattering and Phonon Self-Energy Effects in the R-123 System: Signatures of Gap and Pseudogap
A. Bock
Using Raman spectroscopy and transport measurements we investigate thin epitaxial films of Y{1-x}(Pr,Ca)xBa2Cu3O{6+y}. We explore the electronic Raman responses obtained after subt…
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…
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…
