摘要：

We have made measurements of the conductance of ultrathin oriented layers of YBa2Cu3O7-delta (YBCO) between thicker layers of YxPr1-xBa2Cu3O7-delta [(Y-Pr)BCO] which demonstrate the stepwise progression from submonolayers to bulk-like behavior as the thickness of YBCO is increased iu increments as small as 1 angstrom. The depression of the zero-resistance transition temperature T(KT) is correlated with the depression of the sheet conductance G. For small thicknesses the relation between T(KT) and G is approximately linear and is independent of x. For larger thicknesses there is a transition from this 'surface dependence'' to the dependence in clean bulk material.
