摘要: We have performed the tunnel spectroscopy of energy distribution function quasiparticles in 5-microm-long silver wires connected to superconducting reservoirs biased at different potentials. The f(E) presents several steps, which are manifestations multiple Andreev reflections NS interfaces. rounding steps is well explained by electron-electron interactions.
