My research currently is focused on the electronic transport, film nucleation/growth mechanisms, and the applications of organic compounds such as Pentacene or other interesting compounds/mixtures. In relation TFT's, these interests have led me to study how defects, impurities, and physical limitations to the conduction channel change electronic transport in Pn thin films. These investigations have more recently led me to STM studies of Pn and Pn/C60 in TFT environments. The knowledge I have gained in studying transport limitations and nucleation/growth from an atomic resolution perspective will greatly assist me in future studies aimed at identifying and exploring systems with enhanced electronic transport characteristics or other novel properties. In general, I'm very interested in the relationships between electronic transport, surfaces, defects, impurities, and growth mechanisms. I am also interested in Solar cells, OLED's, Fuel Cells, and many other device related systems.
