Description

This research focuses on investigations of surface and interface electronic structure and ultrafast dynamics at organic heterojunctions with potential applications for organic electronics and LEDs. Topics of interest include determination of band lineup, charge transfer effects at organic/metal, semiconductor interfaces, and the effects organic molecule orientation on surface/interfacial electronic structure. The primary techniques are laser-based time-resolved photoemission and conventional ultraviolet and x-ray photoelectron spectroscopies. Sub-picosecond time-resolved measurements provide detail on charge transfer and recombination processes that determine device efficiency. We are also interested in using polarization effects coupled with theoretical calculations to determine molecular orientation of organic thin films. Complementary techniques based on scanned probes, such as electrostatic force microscopy for surface potential measurements and photovoltage measurements, are also being developed.
