Universal scaling behavior of the c-axis resistivity of high-temperature superconductors

Abstract

We propose and show that the c-axis transport in high-temperature superconductors is controlled by the pseudogap energy and the c-axis resistivity satisfies a universal scaling law in the pseudogap phase. We derived approximately a scaling function for the c-axis resistivity and found that it fits well with the experimental data of Bi${}_2$Sr${}_2$CaCu${}_2$O${}_{8+\delta }$, Bi${}_2$Sr${}_2$Ca${}_2$Cu${}_3$O${}_{10+\delta }$, and YBa${}_2$Cu${}_3$O${}_{7-\delta }$. Our works reveals the physical origin of the semiconductor-like behavior of the c-axis resistivity and suggests that the c-axis hopping is predominantly coherent.
