摘要：

The normal-state thermoelectric power S and resistivity of crystalline Bi2Sr2CaCu2O8-y are strongly influenced by oxygen configuration. In general, the temperature dependences of the coefficients follow simple empirical expressions. For the ab-plane and c-axis thermopower, SA+BT, while for the ab-plane resistivity, T exp[/kBT]. Only A and depend on oxygen configuration. These expressions may hold also for other classes of high-Tc superconducting oxides and are suggestive of and place restrictions on normal-state transport models; normal-state transport models should in turn relate to superconductivity mechanisms. © 1990 The American Physical Society.
