MCW07 Simple Models for Molecular Transport Junctions
13 Sep 2007   Contributor(s):: Misha Galperin, Abraham Nitzan, Mark Ratner
We review our recent research on role of interactions in molecular transport junctions. We consider simple models within nonequilibrium Green function approach (NEGF) in steadystate regime.

MCW07 Electronic Level Alignment at MetalMolecule Contacts with a GW Approach
05 Sep 2007   Contributor(s):: Jeffrey B. Neaton
Most recent theoretical studies of electron transport in singlemolecule junctions rely on a Landauer approach, simplified to treat electronelectron interactions at a meanfield level within density functional theory (DFT). While this framework has proven relatively accurate for certain systems,...

MCW07 Modeling Chargingbased Switching in Molecular Transport Junctions
23 Aug 2007   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...

Electronics From the Bottom Up: a view of conductance
17 Aug 2007   Contributor(s):: Supriyo Datta
Resistance is one of the first concepts an electrical engineer learns, but things get interesting at the nanoscale. Experimentalists have found that no matter how short the resistor is, its resistance cannot drop below a fundamental lower limit. They also found that resistance increases in...
