摘要：

We have used iodine intercalation to alter the interplane interaction and the anisotropic resistivity tensor of the oxide superconductor Bi2Sr2CaCu2Ox. Real-space transmission electron microscopy images confirm that iodine is epitaxially intercalated between the Bi-O bilayers. In the normal state above T(c), the metallic CuO2 plane sheet resistance is unaffected by intercalation, while the out-of-plane conduction is dramatically changed from semiconductorlike to metalliclike. This result is inconsistent with some of the theoretical predictions based on holon-spinon scattering.
