摘要：

Nb-(fine Nb wires)-NbN short weak links (SWLs) have been reproducibly fabricated by field evaporation technique. By this method, we could continuously vary the I-V curve from insulator to tunnel-like and finally to that of metallic contact. The quasiparticle characteristics are qualitatively very similar to the prediction of Klapwijk, Blonder and Tinkham(KBT) theory for the simple case of two independent normal metal-superconductor(NS) interfaces in the clean contact limit.
