We have examined the fabrication conditions of epitaxial CeO 2 films on a-plane sapphire substrates, and also examined epitaxial growth of YBa 2 Cu 3 O 7Γd (YBCO) films on CeO 2 /a-plane sapphire substrate. The h=2h XRD analysis of these composite films revealed that grains of the CeO 2 and YBCO on

Epitaxial CeO2 buffer layers and YBa2Cu307\_~ thin films have been grown in situ on (1].02) sapphire by electron beam evaporation. Buffer layers of only 20 nm thickness inhibit interdiffusion between YBa2 Cu3 O7-6 and A12 03 as determined by depth profiling using x-ray photoelectron spectroscopy. Th
Interracial reactions between thin (approximately 500 A) titanium aluminide films with 30, 50 and 70 at.% aluminum, and both electron-beam evaporated A1203 and sapphire, were investigated with transmission electron microscopy (TEM) and X-ray photoemission spectroscopy (XPS) at 700-900 Β°C.
