摘要：

The ab-plane thermal conductivity of single-crystal Bi2Sr2CaCu2O8-x has been measured from 25 to 300 K, for samples of varying oxygen configuration. Complementary electrical-conductivity measurements on the same crystals allow to be accurately decomposed into electronic and phonon contributions. For metallic samples the electronic contribution to is substantial. Analysis of in the normal and superconducting states allows the defect-scattering and electron-scattering contributions to phonon to be evaluated near Tc. in the superconducting state is consistent with a BCS description. © 1990 The American Physical Society.
