TEM AND STM INVESTIGATIONS OF ANTIMONY PARTICLES DEPOSITED ON GRAPHITE BY MOLECULAR-BEAM DEPOSITION AND LOW-ENERGY CLUSTER BEAM DEPOSITION

Molecular Beam Deposition and Low Energy Cluster Beam Deposition of an timony on graphite are used to produce small supported particles. Para llel TEM and STM investigations of these particles have been performed in order to characterize the first stage of growth. Differences in th e growth modes are observed depending on the deposition technique: in the case of cluster deposition the film builds up by juxtaposition of 3D amorphous particles whereas molecular deposition leads to a competi tion between 2D and 3D growing mode. In addition mobility of the antim ony supported particles on graphite surface has been evidenced.
