We present a technology based on Nb/NbxSi1-x/Nb Junctions. with barriers near the metal-insulator transition, or applications in superconducting electronics (SCE) as an alternative to Nb/AlOx/Nb tunnel junctions Josephson Junctions with co-sputtered amorphous Nb-Si barriers can be made with a wide variety of electrical properties critical current density (J(c)) capacitance (C). and normal resistance (I?) can be reliably selected within wide ranges by choosing both the barrier thickness and NI) concentration Nonhysteretic Nb/NbxSi(1-x)/Nb Junctions with I-c R-n products greater than 1 mV. where I-c is the critical cui rent, and J(c) values near 100 kA/cm(2) have been fabricated and are promising for superconductive digital electronics These barriers have thicknesses of several nanometers. this improves fabrication reproducibility and Junction uniformity. both of which are necessary for complex digital circuits Recent improvements to our deposition system have allowed us to obtain better uniformity across the wafer |
