Abstract |
In the present study the methods of synthesis and characterization of metal nanoparticles
structures of a given size and surface topology on the non-metallic surfaces are
described. The main application of such particles can be selective heterogeneous catalysis
of chemical reactions or their usage as nucleus of growth centers for different
nanostructures (tubes, whiskers, etc.).
The formation of nanoparticles systems on the surface was carried out by two
ways: by "thin cutoff plate" method and by vacuum annealing of ultrathin solid films.
Metal was deposited on the substrate by thermal evaporation (deposition) in vacuum.
Studies of the samples were carried out using the methods of Auger analysis and
scanning electron microscopy. AES detects intense peaks of deposited metals with weak
tungsten (the evaporator material), oxygen, carbon and the substrate material elements
peaks in chemical composition of the films. The SEM studies reveal the presence of
well-defined islet metallic structures on the samples obtained by both methods. For
vacuum annealing method a clear correlation between annealing and obtained structures
parameters is demonstrated.
