Density of states and reflectionless tunneling in NS junction with a barrier
M. Schechter, Y. Imry, Y. Levinson
Abstract
The effect of the barrier on the proximity effect in normal-superconductor junction is analyzed. A general criterion for the barrier, though large, to be effectively transparent, is given. This criterion is applied to both the conductance of a disordered NS junction (reflectionless tunneling) and the density of states across it, showing that both phenomena stem from the same physical effect.
