Transport properties of ultrathin YBa${}_2$Cu${}_3$O${}_{7-\delta }$ nanowires: a route to single photon detection

Riccardo Arpaia, Dmitri Golubev, Reza Baghdadi +6

We report on the growth and characterization of ultrathin YBa${}_2$Cu${}_3$O${}_{7-\delta }$ (YBCO) films on MgO (110) substrates, which exhibit superconducting properties at thicknesses down…
