摘要
The physical properties of nanocermets are related mostly to their morphology. In this contribution, we present the microstructural and morphological evolution of co-sputtered Pt-Al2O3 granular films with thickness, metal concentration and thermal annealing. These investigations are achieved by grazing angle X-ray reflectometry (GAXR), small angle X-ray scattering (SAXS), transmission electron microscopy and atomic force microscopy. The experimental results show that. (1) the diameter of platinum nanoparticles increases as a function of film thickness, annealing temperature and metal concentration; and (2) a columnar growth is observed whose morphology is depending also on the previous parameters and on the growth direction.
