摘要

A simplified model of c axis transport in the high Tc superconductors is presented. Expressions are found for the c axis optical conductivity, the d.c. resistivity, and the c axis penetration depth. Within the framework of this model, the pseudogap in the optical conductivity arises naturally as a result of the layered band structure of the high Tc materials. We discuss the occurrence of the pseudogap in terms of three parameters: a bandgap Δps, a temperature dependent scattering rate Γ(T), and the strength of the interlayer coupling t. We are also able to find analytic expressions for the d.c. conductivity and the low temperature penetration depth in terms of these three parameters. This work is an attempt to present a simple, unified picture of c axis properties in the high Tc cuprates.
