The growth of amorphous solid water and crystalline ice films on various substrates (Pt(111), Pd(111), C(0001) and FeO(111)) is investigated using temperature programmed desorption, rare gas physisorption, specular helium scattering, and infrared spectroscopy. At low temperatures water forms an amorphous film that wets all substrates studied. Heating the amorphous film, or growth at higher temperatures, results in the formation of crystalline ice. Concomitant with crystallization, the water films form non-wetting three dimensional crystallites on either the bare substrate or a substrate covered by only a single monolayer of water. The experimental results and their implications concerning hydrophobicity and the wetting- dewetting transition will be presented.
This work was supported by the U.S. Department of Energy (DOE), Office of Basic Energy Sciences, Chemical Science Division. The experiment and calculations were performed at the W. R. Wiley Environmental Molecular Sciences Laboratory, a national scientific user facility sponsored by DOE’s Office of Biological and Environmental Research and located at Pacific Northwest National Laboratory, which is operated for DOE by Battelle.
