Abstract
Through demonstration of the efficacy of two applications, terahertz anti-reflection and titanium dioxide photocatalysis, we are able to show the limits of the current understanding of the fabrication process, and improve on the models used to predict the porosity. Time domain transmission spectroscopy, surface area, porosity, crystalline structure, and photocatalytic activity are measured and connected back to the parameters used during the deposition process. Models for transmission and porosity demonstrate deviation from experimental results, and a better understanding of the morphology of the films leads to an improved model and can be used to engineer more efficient films.
