The junctions' conductance at room temperature and current-voltage (I-V) characteristics at 4.2 K have been measured after the consecutive stressing of the tunnel barrier at room temperature. Electrical stress was applied using current ramps with increasing amplitude ranging from 0 to ~1000 Ic corresponding to voltages across the barrier up to 0.65 V where Ic is the","authors_text":"2), Denis Amparo (2) ((1) HYPRES, Elmsford, Inc., NY), NY (2) Stony Brook University, Sergey K.
