The thermal conductivity, kappa(T) measurements were performed between 30K and 285K and results obtained found to be between 3.1 and 9.9 mW/cm.K depending an the substitution levels and temperature. Results obtained showed that the phonon-defect scattering dominates above the T-c for all samples but below the T-c a strong coupling mechanism occurs. The best electrical performance was obtained to be 113K and 107K for T-c and T-zero, respectively.eninfo:eu-repo/semantics/closedAccess[No Keywords]Conference Object1173-496396710.1023/A:10225235126642-s2.0-0033354758N/AWOS:000084373900130Q3
