Abstract<\/strong><\/span><\/p>\n

Molecular semiconductors have commercial applications in OLED displays used in mobile phones and TVs, but much is not understood about conduction mechanisms in these materials. In this talk I will describe fundamental measurements in my laboratory aimed at understanding the conductance of molecules on the nanoscale. We explore molecular conductance in two regimes: the tunneling regime, applicable to short molecules less than ~ 5 nm in length, and the polaron hopping regime, which pertains to longer molecules. In the tunneling regime we can achieve very good match between experiments and analytical theory, which opens up exciting opportunities to quantitatively connect structure to conductance. In the polaron hopping regime we observe a very strong kinetic isotope effect, which facilitates understanding of transition states and charge localization effects for intramolecular conductance. In general, the study of molecular conduction mechanisms at the nanoscale provides deeper understanding of transport physics in molecular systems and may someday provide routes to new nanoelectronic or spintronic devices.<\/p>\n

Carl Daniel Frisbie is a Distinguished McKnight Professor of Chemical Engineering and Materials Science at the University of Minnesota where he has been since 1994. Prior to Minnesota, he obtained a PhD in physical chemistry at MIT and was an NSF Postdoctoral Fellow at Harvard. His research focuses on materials for printed electronics, including organic semiconductor thin films and their applications in devices such as thin film transistors and organic solar cells. Research themes include the synthesis and characterization of novel organic semiconductor materials, structure-property relationships in organic electronics, organic device physics, and the application of scanning probe microscopy techniques to electrical characterization. A major focus is the use of gel electrolytes as high capacitance gate dielectrics in organic thin film transistors to boost output currents and lower drive voltages. Carl Daniel Frisbie currently leads a multi-investigator effort in Organic Optoelectronic Interfaces at the University of Minnesota, sponsored by the Materials Research Science and Engineering Center (MRSEC) program of the US National Science Foundation. He is also the lead investigator on a Multi-University Research Initiative (MURI) grant for development of a roll-to-roll printed electronics manufacturing platform. He served as Director of Graduate Studies for Materials Science and Engineering at Minnesota, and has published over 150 scientific papers.<\/p>\n","protected":false},"excerpt":{"rendered":"
