Simulation of synthesis of cluster-assembled nanostructured materials
A model is described to simulate the formation of nanostructured materials by cluster beam deposition. Clusters are modelled by spherical balls with a given size distribution function, which fall to the substrate and stick to the growing structure. The mobility of clusters along the film surface...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | A model is described to simulate the formation of nanostructured materials
by cluster beam deposition. Clusters are modelled by spherical balls with
a given size distribution function, which fall to the substrate and stick to the
growing structure. The mobility of clusters along the film surface is modelled
by introduction of a critical angle at which a falling ball meets a ball
that belongs to the structure. When the falling ball touches one of the balls
in the structure at an angle smaller than the critical one, it sticks to the film;
otherwise the ball rolls along the surface till it meets other balls. It is shown
that a variety of structures similar to those observed experimentally can be
produced. The density of the model structures, percolation thresholds and
the surface roughness are analyzed. |
