Abstract
Results concerning the study of the morphology and the surface chemica l properties of epitaxial YBCO and highly oriented TBCCO films before and after wet etching processes are reported. X-ray photoemission spec troscopy, Auger electron spectroscopy and scanning electron microscopy are employed to get information on the surface contamination and on t he defects of the samples. The chemical modifications of surfaces and the shape of etch pits are discussed.
