Abstract:
The relationship between the open volume defects and the deposition conditions of superconducting thin-film YBa2Cu3O7-x was studied by the position lifetime technique. Using a low-energy pulsed positron system, positron lifetime as a function of implantation energy was measured on epitaxial superconducting thin-film YBa2Cu3O7-x deposited on yttrium stabilized cubic zirconia substrates (YSZ) with pulsed laser deposition in a partial pressure of air under different conditions. The results show that the type of open volume defect is independent of deposition conditions such as the substrate temperature, Ts, and the air pressure, pa. The defect concentration increases with decreasing Ts and increasing pa. «
