1.  Prof. Mark Hersam, Northwestern University, USA
Late-Breaking Results: Infrared Optoelectronic Properties and Applications of Monodisperse Carbon Nanomaterials
Speaker Biography: Mark C. Hersam is currently a Professor of Materials Science and Engineering, Chemistry, and Medicine at Northwestern University. He earned a B.S. in Electrical Engineering from the University of Illinois at Urbana-Champaign (UIUC) in 1996, M.Phil. in Physics from the University of Cambridge in 1997, and a Ph.D. in Electrical Engineering from UIUC in 2000. His research interests include nanofabrication, scanning probe microscopy, semiconductor surfaces, and carbon nanomaterials. Dr. Hersam is a Fellow of MRS and SPIE in addition to serving as the Chair of the AVS Nanometer-scale Science and Technology Division and as Associate Editor of ACS Nano.

Summary: Carbon nanomaterials have recently attracted significant attention in the research community. This talk will highlight our latest efforts to develop solution-phase strategies for purifying, functionalizing, and assembling carbon nanomaterials into functional arrays. For example, we have recently developed a scalable technique for sorting surfactant-encapsulated single-walled carbon nanotubes by their physical and electronic structure using density gradient ultracentrifugation (DGU). The DGU technique also enables graphene to be sorted by thickness, thus expanding the suite of monodisperse carbon nanomaterials. The resulting monodisperse carbon nanomaterials enhance the performance of field-effect transistors, infrared optoelectronic devices, sensors, transparent conductors, and photovoltaics.
