Nanocsale Dynamics and Spectroscopy- Dr. Knappenberger

Members of the Knappenberger research group are working to describe the nano-structure and function interplay and to use these findings to predict the properties of organized nanocluster arrays. Predictive nano-optics have the potential to provide revolutionary breakthroughs in imaging techniques, solar-energy conversion, national security and trace-level analysis. Our multidisciplinary approach encompasses nanoscale synthesis and structural characterization, theoretical predications of optical properties, and the development of advanced spectroscopic techniques to provide structure-specific optical data.
