High-voltage electron microscopy has been improved from a powerful tool for both characterization of the materials to an indispensable "micro-laboratory", and various speciment treatments have been carried out directly and precisely at the atomic scale to give new functional behavior to the materials. In the present paper, the high-voltage electron microscopy "micro-laboratory" is applied to studying atom cluster which behave just like new materials, and the magic size, at which the material behavior markedly changes, is determined on various materials. Furthermore, the atomistic structure and behavior of various atom clusters are discussed based on the experimental results. © 1991.
