Abstract Many different forms of superconducting tunneling have been attempted with the high-T c cuprates. For these studies to be convincing, it is important to assure that elastic tunneling is the dominant conduction mechanism in the structures considered. Some simple criteria to determine whether this is the case are reviewed, and then our results (which satisfy the criteria) on the system Y1−xPrxBa2Cu3O7−δ are discussed. In this study we show that with increasing Pr concentration, the material becomes more gapless.
