摘要：

The in-plane resistivity rho(ab)(T) and the out-of-plane rho(c)(T) have been extensively measured for the pure single-crystal Bi2Sr2CaCu2O8+delta (Bi2212) annealed at different oxygen pressure. The rho(c)(T) and anisotropy [rho(c)(T)/rho(ab)(T)] decreases rapidly with increasing carrier concentration. It is found that the out-of-plane resistivity decreases linearly with temperature down to about 120 K for the overdoped sample; its resistivity anisotropy is a weak temperature dependence. In the ab plane, the anisotropy is very weak and nearly independent of temperature. The data of rho(c)(T) and rho(c)(T)/rho(ab)(T) are well fitted by the bipolaron theory proposed by Alexandrov and Mott. [S0163-1829(98)05945-1].
