“…Thus, carrier lifetimes, for example, can be accurately measured without attenuation due to defect scattering. 8,9 An emerging area of surface science research is the study of organic/inorganic interfaces, 10 which are important for a number of applications, including catalysis, 11 biocompatibility, 12 nanoelectronics, organic electronics, photonics, and photovoltaics, 13Ϫ17 as well as for increasing a fundamental understanding of surface chemistry. A key challenge in studying these interfaces lies in correlating their morphologies with their physical and chemical properties, in particular, their electronic structure.…”
