摘要：

In this work a phenomenological approach to explain experimental tunnel characteristics of high-critical-temperature superconductors presented in a recent paper by Gurvitch et al. [Phys. Rev. Lett. 63, 1008 (1989)] is proposed. More particularly, the influence of proximity effect on the transport properties of these materials is discussed. As shown by the comparison between the computed outcomes and the experimental data, the model reproduces quite closely the experimental behavior.
