摘要：

All-YBa2Cu3O7-x (YBCO) superconductor-insulator-superconductor (SIS) edge-type tunnel junctions have been fabricated. This leads to the observation of superconductive tunneling with very low small-bias conductance for the first time in fabricated all-YBCO junctions. The presence of a superconductive gap of YBCO with a complete suppression of the density of states at the Fermi surface is evident from dynamic conductance measurements. The approach to all-YBCO SIS edge junctions is discussed.
