Abstract

Epitaxial, (001) oriented Y₁Ba₂Cu₃O_7-x thin films were grown on MgO(100) by molecular beam epitaxy at 650°C. The activated oxygen species were produced by a remote microwave-excited discharge in a flow tube. Remarkable improvements of superconducting properties were demonstrated due to enhancements of the flow speed of O₂ stream. The as-prepared films 500Å thick show reproducibly R=0 transitions at 89K, and a ρ{variant}(100K) of 70 μΩ-cm. Ultrathin films 90Å thick still exhibit metallic-like resistivity, and a T_c(R=0) of 70K.
