Abstract

We will discuss several proposed explanations for the switching and negative differential resistance behavior seen in some molecular junctions. It is shown that a proposed polaron model is successful in predicting both hysteresis and NDR behavior, and the model is elaborated with image charge effects and parameters from electronic structure calculations. This model includes the effects of conformational change, charging, and image charge stabilization.
Biography Sina Yeganeh is a graduate student working with Professor Mark Ratner at Northwestern University's Center for Nanofabrication and Molecular Self-Assembly. He received his B.S. in Chemistry from the California Institute of Technology in 2004. His research at Northwestern is supported by a National Defense Science and Engineering fellowship and is focused on the dynamics of charge transport in molecular junctions.

    This is the 5th in a series of annual workshops on Molecular Conduction – the prior workshops have been in W. Lafayette (2003, 2005), Evanston (2004) and Virginia (2006). The workshop has been an informal and open venue for discussing new results and key challenges. Two years ago, we expanded the …
