The device physics and interface chemistry of conjugated polymers are heavily influenced by the transport of both ionic and electronic charge carriers. During the doping of conjugated polymers, ions are introduced for charge compensation. These ions are typically mobile and substantially alter the electric field distribution within and characteristics of conjugated polymer devices relative to analogues based on more traditional inorganic semiconductors. In this talk, the influence of ions on the device physics and chemistry of conjugated polymers and their junctions will be discussed. | 24

Abstract [1]: Carbon nanotube field effect transistors have been shown to be effective low concentration biosensors. Low detection limits are important because it allows for early detection of diseases like cancer. The response of nanotubes to adsorped protein is still not fully understood, and we are investigating this response as a function of flow rate, concentration of protein, and dimensionality of the nanotube sensor. We have used polylysine adsorption as a model system to compare theoretical predictions with experiment | 26
