A Study of 2D GISAXS Patterns of Nanostructured Cerium/Vanadium Oxide Thin Films

Cerium/vanadium mixed oxide films, designed for application in electrochemical cells and electrochemical devices, were obtained on glass substrates by the sol-gel process. An analysis of structural modification of these films, induced by ultrasonification, annealing and by introduction of lithium ions, was performed, using grazing incidence X-ray scattering (GISAXS) technique. Two-dimensional GISAXS spectra were measured at different grazing angles, starting from slightly below the critical angle. One-dimensional scattering curves were extracted from these spectra, showing the dependence of the scattering intensity on different components of the wave vector in the scattering plane. These extractions - "cuts" in differnt directions enable a specific film depth nanostructural profiling.
