By depositing YBaCuO films at low substrate holder temperatures (600 /sup 0/C) using a pulsed laser, films with the orthorhombic phase exhibiting superconductivity with high zero resistance temperatures (T/sub c//sub 0/) were produced. T/sub c//sub 0/ values as high as 50 and 80 K were seen on films deposited directly on Si and on Si with only a 50 nm ZrO/sub 2/ buffer layer, respectively. The key to the successful film deposition is the low processing temperatures involved, which minimized the interface reactions as observed by Auger electron spectrometry.
