Abstract
Superconducting MoGe nanowires with extremely small transverse dimensions have served as unique platforms for exploring physical phenomena in one-dimensional (1D) superconductors. Here we report on networks of superconducting MoGe nanowires with transverse dimensions down to a few nanometers, fabricated by sputter-deposition of MoGe onto commercially available filtration membranes containing dense nanopores. These networks of nanowires exhibit physical properties of individual MoGe nanowires, such as thermally activated phase slips—a dissipation mechanism expected for 1D superconducting nanowires. Furthermore, anomalies in the magnetic field versus temperature phase diagram around 1.2–1.5 Tesla and in the magnetoresistance curves can be understood with the Little–Parks effect, consistent with the multiply connected nature of a network of 1D nanowires.
