An alternative normal state c-axis resistivity model for high-Tc superconductors

Abstract

An alternative model for c-axis resistivity in layered high-Tc crystalline superconductors is proposed and has been characterized as an essentially two-dimensional Fermi liquid. Average ionization energy is included as additional parameter that determines the concentration of tunnelling electrons between Cu-O2 layers. This model agrees well quantitatively with the Bi2212 and Y123 single crystals, and qualitatively with the pure 1212 phase polycrystals.
