    • We have used temperature-independent resistance throughout the paper, since the origin of the temperature-dependent resistance especially for low doping case is not clear at this time. If it is due to Andreev reflection or flux motion of Josephson or Abrikosov vortices in or near the junction, the temperature dependence of the junction resistance may not necessarily be that of bulk barrier resistance.

    • The nominal thickness is based on deposition time. However, the deposition rate in laser ablation is known to change in time and there is a slight change in deposition rate run to run.

    • Tn was found lower than the superconducting transition temperature of a 1000-Å-thick bulk film measured without patterning. It is not unreasonable to assume that thinner films grown on the edges of YBCO patterned into a 4-mum-wide bridge may have a lower Tn, especially given the fact that Tn can change as much as 10 K even in a bulk film depending on the deposition conditions. A slightly different value may be used with reasonable fits to data. However the change in D value due to different Tn value does not affect the systematic conclusions we have found.
