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.

Colloquium on Graphene Physics and Devices
22 Sep 2009 | | Contributor(s):: Joerg Appenzeller, Supriyo Datta, Mark Lundstrom
This short course introduces students to graphene as a fascinating research topic as well as to develop their skill in problem solving using the tools and techniques of electronics from the bottom up.
CQT: Concepts of Quantum Transport
out of 5 stars
30 Nov 2006 | | Contributor(s):: Supriyo Datta
Note: For an expanded version of these lectures see Datta's 2008 NCN@Purdue Summer School presentations onNanoelectronics and the Meaning of Resistance.How does the resistance of a conductor change as we shrink its length all the way down to a few atoms? This is a question that has intrigued...

Nanoelectronic Modeling: From Quantum Mechanics and Atoms to Realistic Devices
30 Dec 2009 | | Contributor(s):: Gerhard Klimeck
The goal of this series of lectures is to explain the critical concepts in the understanding of the state-of-the-art modeling of nanoelectronic devices such as resonant tunneling diodes, quantum wells, quantum dots, nanowires, and ultra-scaled transistors. Three fundamental concepts critical to...
Nanoelectronics and the Meaning of Resistance
20 Aug 2008 | | Contributor(s):: Supriyo Datta
The purpose of this series of lectures is to introduce the "bottom-up" approach to nanoelectronics using concrete examples. No prior knowledge of quantum mechanics or statistical mechanics is assumed; however, familiarity with matrix algebra will be helpful for some topics.Day 1: What and where...
