Abstract

A new electrochemical cell using the oxygen ion conducting solid-state electrolyte, yttria-stabilized zirconia (YSZ), was developed to control the oxygen concentration in high-T_c superconducting Bi₂Sr₂Ca₁Cu₂O_8+x (BSCCO) thin films. In the electrochemical cell, YSZ single crystal plate was used as an oxygen ion pump as well as a substrate for the BSCCO thin film. Oxygen ions were removed from or injected into the BSCCO thin film electrochemically by supplying charges to the cell at 500°C in air. T_c and lattice constant c were found to increase with removing oxygen ions from as-fabricated BSCCO thin films, and to decrease with injecting oxygen ions. These parameters varied reversibly and were correlated, depending on the total charges carried by oxygen ions. It was confirmed that this technique is an effective method to control the oxygen concentration in BSCCO thin films.
