Abstract
The utility of a continuous beam of He droplets for the assembly and surface deposition
of Ag clusters, <N(Ag)> ~ 300 - 6 000, is studied with transmission electron microscopy.
Images of the clusters on amorphous carbon substrates obtained at short deposition
times have provided for a measure of the size distribution of the metal clusters.
The average sizes of the deposited clusters are in good agreement with an energy balance
based estimate of Ag cluster growth in He droplets. Measurements of the deposition
rate indicate that upon impact with the surface the He-embedded cluster is attached
with high probability. The stability of the deposited clusters on the substrate is
discussed.
