Our group is currently studying organic photovoltaics (polymer solar cells), quantum dots, and plasmonics using scanning probe microscopy, optical spectroscopy, single-molecule techniques, and Dip-Pen Nanolithography (DPN). We have developed techniques such as time-resolved electrostatic force microscopy (trEFM) and photoconductive atomic force microscopy (pcAFM).
