Abstract

High-resolution electron microscope (HREM) and computer simulation are used to investigate structural features of gold clusters produced by the inert-gas condensation method. The results indicate that (i) smaller clusters have multiple-twinned-like structure while those larger than 150 Å in diameter show single-crystal structure; (ii) the former cluster consists of either decahedral or icosahedral form and the atomic planes are not strictly parallel and distances between the planes increase towards the cluster edge; and (iii) grain boundaries between the clusters have twin structures with both long- and short-range orders.
