title = "In situ high rate growth of high temperature superconductor tapes",
abstract = "In situ high rate growth of YBa2Cu3O7-δ superconducting films has been carried out using e-beam deposition. A deposition flux controller was developed to monitor and control the deposition rates using tunable diode, laser-based, atomic absorption. A wide range of temperatures, deposition rates, and oxygen fluxes including atomic, molecular oxygen, have been explored in order to understand both kinetic and thermodynamic stability. Critical current density above 1 MA/cm2 has been achieved on SrTiO3 substrate samples with growth rates up to 75 {\AA}/sec. Samples prepared on IBAD YSZ/Ni tapes exhibit similar resistivity properties and x-ray diffraction patterns. However, critical current densities of the tapes are around 5 kA/cm2 or lower. The poor critical current density of the tape is attributed to interactions between the YBa2Cu3O7-δ film and the YSZ buffer layer.",
