DNA Charge Motion: Regimes and Behaviors
28 Jul 2005 | Online Presentations | Contributor(s): Mark A. Ratner
Because DNA is a quasi-one-dimensional species, and
because each base is a pi-type chromphore, it was long ago suggested that DNA could conduct electricity. This has become a widely investigated area, and remains of interest for fundamental science and for applications. We will discuss a very …

MCW07 Modeling Charging-based Switching in Molecular Transport Junctions
23 Aug 2007 | Online Presentations | Contributor(s): Sina Yeganeh, Misha Galperin, Mark A. Ratner
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 …
