Our research program is based on the discovery and quantitative understanding of interfacial electron transfer processes that depend on applied bias in a complex, nonlinear and often asymmetric way. This pursuit is at the heart of efforts to identify and control novel systems that enhance and/or mimic the behavior of conventional semiconductor interfaces, which form the basis for nearly all present day microelectronic devices. An important element of our approach is to understand how the unique chemistry of "new" materials manifests itself in interfacial charge transfer processes. Our studies over the past five years have focused on conjugated or "conducting" polymers where we have been working on three major projects that all draw in some way on the unique redox (doping) chemistry of conjugated polymers relative to more traditional inorganic conductors. Three major areas of research are:

Project 1. Electron transfer at inorganic semiconductor | conjugated polymer interfaces.

Project 2. Polyelectrolyte mediated redox chemistry and inter-faces between dissimilarly doped conjugated polymers.

Project 3. Electron transfer at nanostructured semiconductor interfaces.
