Paper Abstract

We report and analyze the oscillation phenomenon on Cu-26Zn-4Al alloy. The experimental observations indicate that the oscillation patterns manifest distinctly pseudo-fluid behavior in localized areas of micrometer order. By using a fluid mechanics approach, we find that the fluctuation of the adatom cell in the surface layer of Cu alloy exhibits the feature of non-propagating surface solitary wave. The exponential decay of the amplitude with time is in agreement with the measurement. It suggests that this new atom-configuration on the surface of solid materials be of some universality.
