Title	Quartz Crystal Microbalance Measurements of Adsorption Potential Well-Depths
Advisor	Garcia, Rafael, PH
Availability	unrestricted
Abstract Changes in the resonant frequency of a quartz crystal microbalance (QCM), can be used to measure film thicknesses on the order of 0.1 monolayer or less that are adsorbed on the microbalance's electrode surfaces. The well-depth of the adsorption potential for molecules on a flat surface is a key parameter for determining the wetting transition temperature for molecules on that surface. However, it is a difficult quantity to predict with precision using theoretical models. A QCM was used to determine the well-depth of the adsorption potential for for nitrous oxide and other polar molecules on flat surfaces. We compare our data with available theoretical predictions.
