摘要：

We have investigated high temperature electrical resistivity and oxygen diffusion in single crystal Bi2Sr2CaCu2Ox. Above approximately 400-degrees-C, oxygen is readily exchanged with the sample environment which strongly influences the functional form of the resistivity. By changing the partial pressure of oxygen in the sample environment and by continuously monitoring the sample resistance at fixed temperature, we determine oxygen diffusion constants at selected temperatures. In-diffusion is found to be significantly faster than out-diffusion. The in-diffusion data suggest an activated form with a diffusion constant given by D=D0 exp(-E/k(B)T) with D0=11.7 cm2/s and E=1.16 eV.
