The characterization of growth and structure formation in molecular und hybrid e.g. doped systems is an important topic in fundamental organic semiconductor research. In order to study and influence this process different real-time methods have to be used [1]. The growth and structure formation of pure 6-Phenacene as well as the effects of potassium, caesium and rubidium doping were investigated. Thin films of pure 6-Phenacene have been grown in ultra-high vacuum (UHV) and investigated with x-ray, AFM and optical methods. Furthermore, in-situ GIWAXS measurements were performed at PETRA 3 P03. Results on 6-Phenacene as well as preliminary doping results have been published [2]. Doping shows small distortions in crystal structure as well as optical spectra which are yet under investigation and will allow us to get a better understanding on the structural behavior and growth process in theory and experiment.
