SUMMARY:Atomic-scale Exploration of Low-dimensional Materials and Interfaces
DESCRIPTION:        Atomic-scale Exploration of Low-dimensional Materials and Interfaces    Nathan P. Guisinger, PhD    Center for Nanoscale Materials, Argonne National Laboratory          Abstract: Low-dimensional materials functioning at the nanoscale are a critical component for a variety of current and future technologies. From the optimization of light harvesting solar technologies to large- scale catalytic processes, key physical phenomena are occurring at the nanometer and atomic length- scales and predominately at interfaces. For instance, graphene is a nearly ideal two-dimensional conductor that is comprised of a single sheet of hexagonally packed carbon atoms. In order fully realize the potential of graphene for novel electronic applications, large-scale synthesis of high quality graphene and the ability to control the electronic properties of this material on a nanometer length scale are key challenges. This talk will highlight how scanning probe microscopy presents a series of powerful experimental tools that can overcome several challenges and allow for the direct characterization of several advanced materials.                    This talk will cover our efforts to explore synthesis, materials properties, and processing of two- dimensional (2D) materials. I will also present our growth studies and characterization of graphene on a range of substrates that include the first growth on Ag(111) and our investigations of graphene on Ge. Much care must be taken when exploring novel 2D systems, as illustrated by the case study of ?silicene.? Finally, I will cover our most recent studies of amino acids self-assembly relating to surface diffusion and chiral selectivity on Cu(111).    Bio: Nathan P. Guisinger received his Ph.D. in Materials Science and Engineering from Northwestern University in 2005. He is currently a staff scientist at the Center for Nanoscale Materials at Argonne National Laboratory.                         | Event post: https://mie.uic.edu/events?page_id=3348
