Abstract
The production of stable cluster arrays on smooth surfaces has several potential technological
applications. We report a study of the pinning of size-selected palladium nanoclusters on the
graphite surface. The clusters formed during gas aggregation in vacuum are projected with sufficient
kinetic energy to create a defect in the graphite surface. The energy necessary to create such an
immobilizing defect is investigated as a function of the palladium cluster size. The palladium
pinning energy is found to deviate from the simple binary collision model as appropriate to
previously reported silver and gold results. This finding is in agreement with the deviation of nickel
clusters and points to the influence of the interatomic cluster bonding on the mechanics of the
collision.
