| 报告介绍 | Abstract：
In molecular conductance spectroscopy, the current through a molecule (or molecules) connecting two metal or semiconductors electrodes is measured as a function of the applied voltage. With eye on potential technological applications the main problems facing researchers in this field fall within the subjects of fabrication, characterization, stability, functionality and control. This talk will review recent progress in understanding molecular conduction with particular emphasis on the role played by the molecular electronic structure and conformation, its coupling to the electrodes and its interaction with the underlying nuclear motion and the thermal environment. As a theoretical problem, one needs to deal with a non-equilibrium system open to electron and energy reservoirs, possibly under illumination. We will focus on relative timescales of different processes as a way to assess their importance in the overall conduction. Characterization, stability functionality and control will be discussed in the framework of recent studies on inelastic tunneling spectroscopy, heating and heat conduction in molecular junctions and magnetic and optical response of such systems.
Biosketch: Abraham Nitzan was born in Israel in 1944, received B.Sc. and M.Sc. degrees from the Hebrew University, and Ph.D degree from Tel Aviv University (TAU) in 1972. Following post doctoral studies at MIT and the University of Chicago he has returned to Tel Aviv University in 1975 where he is a professor of Chemistry since 1982 (Emeritus since 2014). In summer 2015 he became a professor of Chemistry at the University of Pennsylvania. At TAU he has served as Chairman of the School of Chemistry in 1984-7, Dean of the Faculty of Sciences in 1995-8 and director of the Institute of Advanced Studies 2003-15. His research focuses on the interaction of light with molecular systems, chemical reactions in condensed phases and interfaces and charge transfer processes in such environments. He has published over 300 papers, a comprehensive text ("Chemical Dynamics in Condensed Phases", Oxford U. Press, 2006), was assigned one patent and has given invited talks in over 150 scientific meetings.
During 1992-2015 Nitzan was the incumbent of the Kodesh Chair of Chemical Dynamics at Tel Aviv University. Among his main recognitions are the Humboldt Award, the Israel Chemical Society Prize (2004) and Medal (2015), the Emet Prize and the Israel Prize in Chemistry. He is a Fellow of the American Physical Society and of the American Association for the Advancement of Science, a Foreign Honorary member of the American Academy of Arts and Sciences, a Foreign Associate of the US National Academy of Sciences and a member of the Israel Academy of Arts and Sciences. In 2010 he has received an honorary doctorate (Dr. Honoris Causa) from the University of Konstanz. |
