Abstract
We report the experimental results on the investigation of superconducting double-barrier structures with niobium interlayer and Al2O3 barriers. The experimental results can be explained by an extreme enhancement of superconductivity in the interlayer in accordance with the quasiparticle balance model, where the energy dependence of the inelastic relaxation time of quasiparticles with energy close to the superconducting gap is taken into account. © 1996 The American Physical Society.
