Abstract

A theoretical analysis of thermal conductivity of high-temperature superconductor cuprates, Pr<subscript>1.3−x</subscript>La<subscript>0.7</subscript>Ce<subscript>x</subscript>CuO<subscript>4</subscript> (PLCCO), has been successfully investigated. In this formulation, the idea of relaxation times and other scattering processes has been developed from frequency (energy) line widths using a quantum dynamical method. The major emphasis of this study is on the influence of phonon-dopant atom scattering on the thermal conductivity of Ce-doped PLCCO, as well as other prominent scattering processes such as electron-phonon, cubic and quartic anharmonic phonon, cubic and quartic phonon interference, and so on. The proposed theory has achieved a satisfactory agreement between theory and experiment. [ABSTRACT FROM AUTHOR]
