Abstract
The study of nuclei of Au deposited on NaCl substrates cleaved in the ultrahigh vacuum shows that most small deposits on the flat parts of the substrate are multiply twinned particles, whereas, at the cleavage steps there are epitaxial particles of definite shapes with either (100) or (111) orientation. From the dependence of the shape of small deposits on the magnitude of the interfacial interaction and from the stability of the multiply twinned particles, it is concluded that the predominant existence of multiply twinned particles is an indication of negligible interfacial interaction while the existence of epitaxial particles at the steps is due to the creation of nucleation sites by surface defects. The loss of epitaxy of Au on NaCl cleaved in an ultrahigh vacuum is explained as the result of negligible interfacial interaction between the deposits and substrates.
