Superconducting nanowire quantum interference device based on Nb ultrathin films deposited on self-assembled porous Si templates
C. Cirillo, S. L. Prischepa, M. Trezza +2
Magnetoresistance oscillations were observed on networks of superconducting ultrathin Nb nanowires presenting evidences of either thermal or quantum activated phase slips. The magn…
Nonlinear current-voltage characteristics due to quantum tunneling of phase slips in superconducting Nb nanowire networks
M. Trezza, C. Cirillo, P. Sabatino +3
We report on the transport properties of an array of N about 30 interconnected Nb nanowires, grown by sputtering on robust porous Si substrates. The analyzed system exhibits a broa…
Quantum phase slips in superconducting Nb nanowire networks deposited on self-assembled Si templates
C. Cirillo, M. Trezza, F. Chiarella +4
Robust porous silicon substrates were employed for generating interconnected networks of superconducting ultrathin Nb nanowires. Scanning electron microscopy analysis was performed…
Evidence of fractional matching states in nanoperforated Nb thin film grown on porous silicon
M. Trezza, C. Cirillo, S. L. Prischepa +1
Resistive transitions have been measured on a perforated Nb thin film with a lattice of holes with the period of the order of ten nanometers. Bumps in the dR/dH versus H curves hav…
Superconducting properties of Nb thin films deposited on porous silicon templates
M. Trezza, S. L. Prischepa, C. Cirillo +9
Porous silicon, obtained by electrochemical etching, has been used as a substrate for the growth of nanoperforated Nb thin films. The films, deposited by UHV magnetron sputtering o…
