The reflection high energy electron diffraction (RHEED) method has been used for the
investigation of Au cluster growth on KCl substrate. The formation of three-dimensional
particles was observed. The morphological parameters of the particles (i.e. diameter and
density) were estimated ex-situ by transmission electron microscopy (TEM) and the results
were compared with the RHEED spot profiles. Au particles were chosen, because they did not
change their parameters by the reconstruction caused by oxidation during the preparation
for TEM measurements.
