WETTING TRANSITIONS OF CLASSICAL LIQUID-FILMS - A NEARLY UNIVERSAL TREND

We calculate wetting behavior for the adsorption of Ne, Ar, Kr, and Xe for temperatures above their triple point. Experimental observations of wetting transitions of these simple liquids are predicted. We also report a nearly universal trend in the physical interaction parameters for Ar, Kr, and Xe on various substrates. With a simple model, we sho w that the classical ''law of corresponding states'' can be extended t o predict approximately universal behavior in the wetting transitions of these films. We then demonstrate, by comparison with Ne, Hz, and He films, that quantum effects enhance wetting in that there is a larger range of adsorption parameters leading to wetting when zero-point mot ion is included.
