Axial ion channeling in as-deposited high-T/sub c/ Y-Ba-Cu oxide superconducting thin films on (100) SrTiO/sub 3/ and x-ray photoelectron spectroscopy (XPS) on the film surfaces were performed. The angular yield profile near the film for Ba and the surface peak intensity were measured using 3-MeV He ions. For channeling normal to the substrate, a minimum yield of 7%, compared to approx.2%--3% for single crystals, was obtained. The results of ion channeling and XPS studies indicate that the as-deposited films have good crystallinity as well as stoichiometry to within approx.1 nm of the film surface.
