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.

20 Sep 2006 | Publications | Contributor(s): Jing Guo, Supriyo Datta, Mark Lundstrom, M. P. Anantram
Multiscale simulation approaches are needed in order to address scientific and technological questions in the rapidly developing field of carbon nanotube electronics. In this paper, we describe …
Quantum Transport for Nanostructures
17 Sep 2006 | Publications | Contributor(s): Mathieu Luisier
Nonequilibrium Green's function techniques, initiated by Schwinger and Kadanoff and Baym allow ones to study the time evolution of a many-particle quantum sys- tem. Knowing the 1-particle Green's …
Exploring New Channel Materials for Nanoscale CMOS
21 May 2006 | Publications | Contributor(s): Anisur Rahman
The improved transport properties of new channel materials, such as Ge and III-V semiconductors, along with new device designs, such as dual gate, tri gate or FinFETs, are expected to enhance the …
Device Physics and Simulation of Silicon Nanowire Transistors
20 May 2006 | Publications | Contributor(s): Jing Wang
As the conventional silicon metal-oxide-semiconductor field-effect transistor (MOSFET) approaches its scaling limits, many novel device structures are being extensively explored. Among them, the …
Notes on the Ballistic MOSFET
08 Oct 2005 | Publications | Contributor(s): Mark Lundstrom
When analyzing semiconductor devices, the traditional approach is to assume that carriers scatter frequently from ionized impurities, phonons, surface roughness, etc. so that the average distance …
Electrical Conduction through Molecules
08 Jul 2003 | Publications | 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 …
