High dynamic resistance elements based on a Josephson junction array
A chain of superconductor–insulator–superconductor junctions based on Al–AlO(x)–Al nanostructures and fabricated using conventional lift-off lithography techniques was measured at ultra-low temperatures. At zero magnetic field, the low current bias dynamic resistance can reach values of ≈10(11) Ω. I...

| Sumario: | A chain of superconductor–insulator–superconductor junctions based on Al–AlO(x)–Al nanostructures and fabricated using conventional lift-off lithography techniques was measured at ultra-low temperatures. At zero magnetic field, the low current bias dynamic resistance can reach values of ≈10(11) Ω. It was demonstrated that the system can provide a decent quality current biasing circuit, enabling the observation of Coulomb blockade and Bloch oscillations in ultra-narrow Ti nanowires associated with the quantum phase-slip effect. |
