Deposition of antimony and bismuth onto HOPG
Highly oriented pyrolytic graphite provides an extremely smooth surface
on which the fundamental processes involved in diffusion and
aggregation
of atoms and clusters can be studied. Shelley Scott, as part of her PhD
project, has performed extensive studies of the diffusion of both Sb4
tetramers and Bi2 dimers on HOPG.
