説明
Abstract Growth kinetics of multiply twinned particles (MTP's) of Ag and Au formed by vacuum deposition on MgO and MoS 2 were studied by in-situ electron microscopy. Three types of growth process were observed: (1) a MTP nucleated ab initio and grown to a certain size while maintaining its equilateral shape; (2) a small MTP re-formed after coalescence of a MTP with another MTP or an epitaxial particle; and (3) a MTP formed by a successive twin formation starting from an epitaxial particle. Based on these observations, the growth mechanism is discussed with recognition that a MTP is a stable or metastable entity of a small cluster of atoms. Stress is laid on the importance of stability considerations rather than on the detailed growth model obtained by adding atom-by-atom.
