Abstract

Small Ag and C particles, about 10 nm in diameter, are produced in gas suspension and precipitated on HOPG substrates for STM analysis. The STM pictures showed much smaller particle concentrations than anticipated from parallel TEM studies. The particles appear very flat in STM, not spherical as expected. These effects could be attributed to the nature of interaction between particle and surface, or to the interaction between tip and particle. Many of our experimental results are consistent with particles moving under the influence of the scanning tip.
