OFF-SPECULAR X-RAY-SCATTERING STUDIES OF THE MORPHOLOGY OF THIN-FILMS

We discuss the scattering of X-rays from thin films at a surface or in terface decorated with a morphology of islands and how these effects m anifest themselves in the specular reflectivity and the diffuse (off-s pecular) scattering. We show how this technique has been used to study block copolymer films decorated with islands on the surface and the d evelopment of electrochemically induced pitting on a Cu electrode in a n electrolyte solution.
