Abstract

We have measured I(V) characteristics of c-axis planar tunnel junctions on Y₁Ba₂Cu₃O_7-δ films. Our results and their analysis provide experimental support for the importance of the two-dimensional character of the YBCO band structure, and a method to measure the ratio between the Fermi energy of YBCO and the barrier height. The analysis is based on the relation between the linear conductance background, related to the inelastic tunneling component, and the zero bias conductance, related to the elastic one.
