    Notes: Abstract The adhesion of small particles of palladium prepared by thermal evaporation onto a substrate of Al2O3 was studied. Al2O3 was obtained by oxidation of a pollycristalline aluminum strip. The deposit of palladium was observed by Transmission Electron Microscopy which allowed to determine the size and the density of particles according to the average deposition thickness. The adhesion of particles was determined by two methods: the study of particle number density, and the study of the particle shapes.

    Growth mechanism of gold particles on Al2O3 substrates (1991)
    Springer
    The European physical journal 19 (1991), S. 311-313

    Notes: Abstract We investigated the growth of small gold particles on thin alumina substrates obtained by oxidation of aluminum. The particles were vapor deposited in vacuum from a Knudsen cell source with a vapor rate of 1·1013 cm−2·s−1. In our experiments small Au particles on Al2O3 were examined by electron microscopy. From electron micrographs we draw a size histogram of Au particles depending on the mean deposit thickness and the deposition rate. For a mean thickness larger than 1.5 nm the particle size distributions show two peaks. The shapes and the positions of these two peaks allow us to determine the particle growth mechanism and to evidence the importance of the liquid-like coalescence resulting of diffusion and collision of the aggregates.
