Abstract
We have deposited small numbers of atoms of silver, gold, and aluminum onto cleaved graphite substrates in ultrahigh vacuum. Using a scanning tunneling microscope, we have observed monomers, groups of monomers, dimers, and a trimer. The adsorption sites and atomic spacings are determined by direct observation.
