|Title:||Free-carrier relaxation dynamics in the normal state on sintered YBa2Cu3O7-y|
|Published:||August 01, 1987|
|Abstract:||The conductivity of YBa2Cu3O7-y in the normal state has been obtained from a measurement of the reflectivity over a wide frequency range. The product of the Drude model parameters Wpt<1 indicates that the plasma oscillations are overdamped. The free-carrier electrodynamics are well described by a frequency-dependent scattering rate which rises linearly in frequency from the dc value and saturates at a value consistent with scattering at the unitarity limit with a concomitant frequency-dependent mass enhancement,|
