Abstract
An alternative model for c-axis resistivity in layered high- T c crystalline superconductors is proposed and has been characterized as an essentially two-dimensional Fermi liquid. Average ionization energy is included as an additional parameter that determines the concentration of tunneling electrons between Cu–O 2 layers. This model agrees well quantitatively with the Bi2212 and Y123 single crystals, and qualitatively with the pure 1212 phase polycrystals.
