Abstract

Clusters of Au and Ag deposited on the surface of highly oriented pyrolitic graphite have been imaged in air using a scanning tunneling microscope. An image is shown of a 350-Å silver cluster obtained in the constant-current (topographic) mode. In the variable-current mode, clusters of 6-20 atoms have been observed with atomic resolution. The motion and growth of clusters on the support are observed.
