Abstract:
Data of water adsorption on polycrystalline gold show the formation of a multilayer film of several nanometers with the increase of relative humidity. We have measured this adsorption process by scanning force microscopy in both dynamic and jumping modes. We find interesting differences in the adsorption of water on the terraces and at grain boundaries. Measurements of adhesion force are also reported.
