Theoretical modeling of charge transport in conjugated-polymer materials

Assistant Professor of Chemical Engineering and, by courtesy, of Materials Science and Engineering

Semiconducting polymers play an important role in a wide range of optical and electronic material applications.  It is widely accepted that the polymer ordering impacts charge transport in such devices. However, the connection between molecular ordering and device performance is difficult to predict due to the current need for a theoretical model for charge transport in semiconducting polymers.  I will present a new theory of charge transport that captures the intrachain and interchain hopping through an amorphous conjugated polymer environment.  This effort provides the first method to predict the role of polymer conformation in device performance.
