• The etching effect of fine gold particles evaporated on a graphite surface was investigated in this study. Goldparticles with diameters around 2-3 nm deposited on graphite coagulate to form 10-100 nm-diameter particles during annealing at about 400℃. Furthermore, at the same time, it was found that the coagulation was accompanied by etching of the graphite substrate. For highly oriented pyrolytic graphite (HOPG), the same phenomenon was observed. On the other hand, no etching phenomenon was observed for a diamond surface. The oxidation reaction of graphite at the interface between gold particles and graphite by residual gas molecules in vacuum is greatly enhanced by the catalytic effect of gold particles.
