Abstract :
The in situ growth of YBa2Cu3O7 thin films has been studied using e-beam coevaporation. The growth conditions for smooth YBa2Cu3O7 films with high Tc and Jc have been established. Superconductor-insulator (SI) and superconductor-insulator-superconductor (SIS) structures have been grown using Y2O3 as an epitaxial insulator, and preliminary vertical transport measurements in patterned structures are reported
