We have utilized white x-ray beam and a Ge solid state detector, in energy dispersive mode, to study the diffraction from the surface layers of ceria deposited on (001) surface of Y stabilized cubic zirconia with grazing incident beam. We found that ceria forms islands, oriented epitaxially with respect to the zirconia substrate, with a lateral coherence of the order of 60 Å.
