Organic molecular crystalline (OMC) films are being investigated for use in a wide range of potential applications, from field effect transistors, to light-emitting diodes, and photovoltaic cells. The ultimate utility of OMC materials for such applications will depend on the degree and type of molecular order in deposited films, as well as the processing costs for preparing them. The goal of this thesis is to develop a method to produce high quality OMC thin films under ambient conditions, to characterize those films, and their growth kinetics. In particular, I will investigate OMC film growth by ambient axisymmetric spray method, a technique in which an organic semiconductor is sublimated into a carrier gas at ambient pressure and deposited onto a substrate coated with a thin liquid layer. I will examine the growth kinetics and morphologies of the resulting films. The results of this research will be an improved understanding of the growth of organic crystals in a thin film of liquid and the production of cheap organic semiconductor thin films
