Organic semiconductors have received intense interest over the past fifteen years due to their potential in enabling low cost, printable and flexible electronics with proposed applications ranging from large area flexible displays to photovoltaics. One of the great challenges in organic electronics is to understand the interplay between extrinsic parameters such as fabrication processes, environmental effects and device history and intrinsic parameters such as molecular structure and morphology. This seminar will discuss two specific extrinsic phenomena that are important to the further development of organic electronics. In the first part of the seminar, the impact of oxygen as an electron transfer dopant in rubrene single crystal devices will be discussed. The second half of the talk will discuss the effect of nanocomposite dielectric structure on performance in organic thin film transistors.
