- The atomic force microscope has been used in the attractive (noncontact)
force mode to produce images of individual nanometer-size clusters pre-formed
in the gas phase and deposited on a wide variety of atomically-flat
substrates. Using this technique, it is now possible to reliably image
pre-formed clusters in their as-deposited positions. Studies of
nanometer-size Au clusters supported on highly oriented pyrolitic graphite
clearly show how the clusters are distributed across the scanned region.
Cluster coverages inferred from atomic force studies are compared to those
obtained from TEM studies of amorphous carbon grids simultaneously exposed to
the same cluster beam. (18 References).
