Phonon anomalies and range of superconducting energy gaps from infrared studies of YBa2Cu3O7- delta.
TL;DR: The oscillator strengths of the experimentally observed phonons are all stronger than those from a lattice-dynamics model which assumes ionic charges close to the formal ones, especially so for the lowest phonon found at 155 cm/sup /minus/1/ which shows a strength about 15 times higher than theoretically expected.

Systematic Raman and infrared studies of the superconductor YBa2Cu3O7-x as a function of oxygen concentration (0≦x≦1)
Christian Thomsen,R. Liu,M. Bauer,A. Wittlin,L. Genzel,Manuel Cardona,E. Schönherr,W. Bauhofer,W. König +8 more
TL;DR: In this paper, the variation of Raman and infrared spectra of the new high T c superconductors with oxygen content was studied and it was shown that the Raman peaks associated with Cu-O stretching vibration (502 cm −1, x=0) and Ba-O vibrations (154 cm − 1, x = 0) decrease in frequency when oxygen is removed.

Optical conductivity of BCS superconductors with arbitrary purity
TL;DR: In this paper, an explicit expression for the complex optical and AC conductivity of a homogeneous BCS superconductor with arbitrary electron mean free path is given, and a fast self-contained FORTAN program may be used to fit experimental data.

Raman and infrared studies of the oxygen deficient semiconducting phase of the superconducting cuprate perovskites
Christian Thomsen,Manuel Cardona,W. Kress,R. Liu,L. Genzel,M. Bauer,E. Schönherr,U. Schröder +7 more
TL;DR: In this paper, the authors report Raman and far infrared spectra of the semiconducting (O6) defect perovskites MBa2Cu3O6 and compare them to the spectra found in the high Tc superconductors (O7).
