Abstract
Nanometer-sized clusters of copper have been produced in a hollow
cathode sputtering source and deposited on SiOx. Halo-like
structures consisting of micrometer sized protrusions in the
solicon oxide surface surrounded by thin rings of smaller
particles are observed. The area in between seems to be depleted
of particles. We propose that the halo-like structures are a
result of electrostatic forces acting between the incoming charged
clusters and charged regions on the surface. A simple computer
simulation supports this suggestion.
