Abstract
We have employed a quartz crystal microbalance technique to study the thickness versus pressure dependence of a variety of thin (0–5 nm) liquid films (water, cyclohexane, nitrogen, krypton, and xenon) adsorbed on metal surfaces. We observe the Lifshitz theory of van der Waals forces to provide an excellent description of nitrogen adsorption, and an inadequate description of water adsorption, with the remaining gases spanning the two extremes.Keywords
