Description

The phonon drag thermoelectric power S (T) of electron (Nd1.82Ce0.18CuOy) and hole (YBa2Cu3O7-δ) doped cuprate superconductors are theoretically analysed within the relaxation time approximation. Mott expression is used to generate the carrier diffusive thermoelectric power (Scdiff). The theory is formulated when heat transfer is limited by the scattering of phonons from defects, grain boundaries, phonons, tunnelling states and charge carriers. The phonon drag thermoelectric power (Sphdrag) dominates and is an artefact of strong phonon-impurity and -phonon scatterings. The anomalies reported are well accounted in terms of the scattering mechanism by phonon drag and carrier scattering with impurities. (author)
