Analysis of the formation of vapor-deposited organic thin films using quartz crystal microbalance
An optimization of preparation parameters and a detailed study on growth kinetics for organic thin film are required to obtain high functional devices, coatings and sensors. In this study, the deposition behavior of organic molecules during physical vapor deposition was observed in real time by a quartz crystal microbalance technique which is widely used as a thickness monitor method. Moreover, the mean adsorption time of vapor-deposited organic molecules on substrate was estimated from the result of fitting of a theoretical rate equation based on a physisorption model to experimental data.
