A systematic optical study of phonon properties in optimally doped Bi2Sr2CaCu2O8+d single crystals
A systematic optical study of infrared-active phonons is carried out for optimally doped Bi2Sr2CaCu2O8+d (Bi2212) single crystals with E-vector along c-axis as well as in the ab-plane at 295K. Strong phonon anisotropy has been observed in our ab-plane conductivity measurements. Ten infrared-active phonons have been observed along c-axis. Many of these c-axis infrared-active phonons have energie...
متن کاملA Systematic Optical Study of Phonon Properties in Optimally Doped Bi2Sr2CaCu2O8+δ Single Crystals
Infrared spectroscopy is often used to investigate the question of electron-phonon interaction in ‘bad’ metals, particularly in high Tc cuprates, because both the electronic properties and phonon properties can be studied simultaneously. In view of the renewed suggestion that charge-phonon coupling is the mechanism for superconductivity in high Tc cuprates, charge-phonon interaction needs to be...
متن کاملInfrared conductivity of a dx2-y2-wave superconductor with impurity and spin-fluctuation scattering.
Calculations are presented of the in-plane far-infrared conductivity of a dx2−y2-wave superconductor, incorporating elastic scattering due to impurities and inelastic scattering due to spin fluctuations. The impurity scattering is modeled by short-range potential scattering with arbitrary phase shift, while scattering due to spin fluctuations is calculated within a weak-coupling Hubbard model p...

Submitted for the MAR06 Meeting of The American Physical Society Strong correlation effects in the IR Hall Effect in the cuprates: an overview1 H.D. DREW, University of Maryland — The Hall Effect at infrared frequencies provides a sensitive probe of strong interaction effects in strongly correlated metals. Experimental results show that the strong interaction effects inter the Hall conductivity...
