CFN Research Activities

We have a strong record in developing novel quantum chemistry methods in density functional theory.  Our most recent development is a density-based energy decomposition analysis for intermolecular interactions.  We are also experts in constrained density functional theory and its application to electron transfer.  Our current research is focused on electronic processes in organic materials, such as the generation, separation and transport of charges in organic photovoltaics and thin film transistors.  We use quantum calculations to probe the interactions between molecules and those between charges and the molecular structures.  We study the implication of these interactions to the performance of real devices.  We then make recommendations to experimental colleagues on materials synthesis and processing, and device fabrication.
