Notes:
We studied the effects of ultraviolet (UV) irradiation in an ozone atmosphere on the electrical properties of Ba2 YCu3 O7−x thin films. The ozone-UV treatment had effects similar to plasma oxidation; it decreased the room-temperature resistivity and increased the zero resistance temperature of 460 nm Ba-Y-Cu-O thin films. Film resistivity decreased by about 25% in 100 min during ozone-UV treatment. This decreasing rate is one order of magnitude lower than plasma treatment. The ozone-UV treatment, however, resulted in a more stable film than the plasma treatment. The rate at which the room-temperature resistivity increased, measured 35 days after the ozone-UV treatment, was 0.06%/day, or about 1/6 that of the plasma treatment.
