摘要：
The morphology of ceramic-metal (cermet) thin films is studied by surface-sensitive X-ray scattering techniques. Grazing incidence small angle X-ray scattering (GISAXS) experiments carried out at LURE with a 2D detector show that metal clusters of nanometer size, known as nanoparticles, are dispersed in the thin film. Analyses of the X-ray reflectivity along with the diffuse scattering allow to predict the formation of layers of nanoparticles along the growth direction of the films. The formation of such cumulative-disordered layers in one direction is likely to be related to the boundary condition in the reduced dimension. (C) 2000 Elsevier Science B.V. All rights reserved.
