Abstract
We study the nonlinear transport properties of NS (normal-superconductor) and NSN structures by means of a self-consistent microscopic description. A nonzero superfluid velocity causes the various quasiparticle channels within S to open at different voltages. The gap reduction is very sensitive to the details of quasiparticle scattering. At low temperatures, superconductivity, some times in a peculiar gapless form, may survive up to voltages much higher that . The minimum voltage for quasiparticle transmission is shown to decrease strongly with temperature and with the transmittivity of the barrier.
