摘要：

Metal growth processes of Pd clusters on mica were studied using atomic force microscopy (AFM). The Pd clusters formed were hemispherical until the cluster size was below 1.0 x 10(4) atom.cluster(-1). However, when the cluster size exceeds this value, the cluster shape was dramatically changed to thinner and flatter. Here, the Pd clusters were self-ordered into microcrystals. These phenomena can be explained in terms of the unit surface energy of the clusters. (C) 1998 Acta Metallurgica Inc.
