Our results suggest that at low temperatures the mean free path of carriers in the chains is mainly determined by scattering at oxygen vacancies, while at higher temperatures scattering at phonons occurs additionally.

Europhysics Letters (EPL), 1991

ABSTRACT We report on a study of far-infrared and microwave intragap absorption of a YBa2Cu3O7-δ ... more ABSTRACT We report on a study of far-infrared and microwave intragap absorption of a YBa2Cu3O7-δ thin film at low temperature. Our results suggest a superconducting energy gap with 2Δ(0)/kBTc ≈ 7 and residual, intragap absorption for temperatures T Tc that consists of three portions, a microwave and a far-infrared band of possibly nonintrinsic nature and sharp phonon resonances of intrinsic nature.
