Ion-beam modification of high-temperature superconductor thin films for the fabrication of superconductive nanodevices


Ion-beam irradiation allows for a direct modification of the electric properties of high-temperature superconductors (HTS). Computer simulations of the ion-target interactions reveal that He+ions at energies above 60 keV do not implant into 100-nm thick films of YBa<inf>2</inf>Cu<inf>3</inf>O<inf>7</inf>but can create about one defect per unit cell at… (More)
