    • At this low coverage there is no sign of a preference for the adatoms to cluster on the terraces or bind to step edges. This places an upper limit on any adatom transient mobility across the surface during the adsorption process.

    • Voltage ramps typically required app 10 sec. Drift of the STM tip with respect to the sample was negligible during this time.

    • Single atoms from the tip were deposited onto the surface by gently ``contacting'' the STM tip to the surface (junction impedance app 60 kOMEGA), and then retracting the tip. This process was tip dependent.

    • Some justification for assuming a constant ρPt(E) is that the tip was sufficiently far from the surface (app 6 Å) that one can expect the measured current to be dominated by electrons tunneling to and from s- and p-like states at the surface. For the energy range probed in this experiment (EF+- 1.0 eV), the bulk densities of these states in Pt are relatively featureless.
