Electrochemical Deposition of Silver Nanocrystallites on the Atomically Smooth Graphite Basal Plane,

These six NC-AFM images show silver nanocrystallites prepared by pulsed electrochemical deposition from a dilute silver electrolyte on the atomically smooth (or nearly so, you can see some step edges!) graphite basal plane. Three silver coverages, increasing from left to right are shown: LEFT- QAg = 0.315 x 10-6 C cm-2, MIDDLE- QAg= 7.54 x 10-6 C cm-2, RIGHT- QAg = 16.0 x 10-6 C cm-2. For purposes of comparison, QAg= 350 x 10-6 C cm-2 is approximately equivalent to one silver monolayer. These particles were prepared by pulsed potentiostatic deposition from dilute solution using a procedure described in this paper.
