Abstract
The surface-diffusion process of tungsten atoms and clusters on magnes ium oxide (001) surfaces is observed directly by high-resolution elect ron microscopy (HREM) with time resolution of 1/60 sec. It is found fr om the data reproduced from video-tape images that the diffusion proce ss is classified into a short-jump process to neighboring sites and a long-jump process over a l-nm distance. The present observation indica tes a new potential for the study of the surface-diffusion process wit h HREM.
