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