The non-equilibrium Greens function (NEGF) formalism provides a powerful conceptual and computational framework for treating quantum transport in nanodevices. It goes beyond the Landauer approach for ballistic, non-interacting electronics to include inelastic scattering and strong correlation effects at an atomistic level.
Check out Supriyo Datta's NEGF page for more information, or browse through the various resources listed below.
MATLAB Scripts for "Quantum Transport: Atom to Transistor"
out of 5 stars
15 Mar 2005 | | Contributor(s):: Supriyo Datta
Tinker with quantum transport models! Download the MATLAB scripts used to demonstrate the physics described in Supriyo Datta's book Quantum Transport: Atom to Transistor. These simple models are less than a page of code, and yet they reproduce much of the fundamental physics observed in...
NanoMOS 2.5 Source Code Download
22 Feb 2005 | | Contributor(s):: , Sebastien Goasguen
NanoMOS is a 2-D simulator for thin body (less than 5 nm), fully depleted, double-gated n-MOSFETs. A choice of five transport models is available (drift-diffusion, classical ballistic, energy transport, quantum ballistic, and quantum diffusive). The transport models treat quantum effects in the...

Understanding Molecular Conduction
08 Jul 2004 | | Contributor(s):: Supriyo Datta
It is common to differentiate between two ways of building a nanodevice: a topdown approach where we start from something big and chisel out what we want and abottom-up approach where we start from something small like atoms or molecules andassemble what we want. When it comes to describing...

Electrical Conduction through Molecules
08 Jul 2003 | | Contributor(s):: Ferdows Zahid, Magnus Paulsson, Supriyo Datta
In recent years, several experimental groups have reported measurements of the current-voltage (I-V) characteristics of individual or small numbers of molecules. Even three-terminal measurements showing evidence of transistor action has been reported using carbon nanotubes as well as...
