Abstract
Single crystalline films of YBaCuO have been epitaxially prepared for the first time on sapphire substrates at temperatures as low as 500βC by the metalorganic chemical vapor deposition method. The starting materials were Y(HFA)3, Ba(HFA)2, and Cu(AcAc)2. Deposition was carried out with an oxygen pressure of 10 Torr. Electron probe measurements and Auger electron spectroscopy suggest that the constituent of the film is YBa2Cu3Ox. Carbon has not been detected in the film. Spots and streak patterns obtained in the electron diffraction measurements suggest high crystalline quality and smoothness of the surface.
