20 Aug 2008 | Online Presentations | Contributor(s): Supriyo Datta
This lecture provides a brief overview of the five-day short course whose purpose is to introduce a unified viewpoint for a wide variety of nanoscale electronic devices of great interest for all …
Lecture 1A: What and where is the resistance?
Objective: To introduce a simple quantitative model that highlights the essential parameters that determine electrical conduction: the density of states in the channel, D and the rates at which …
Lecture 1B: What and where is the resistance?
Lecture 2A: Quantum Transport
Objective: To extend the simple model from Lectures 1 into the full-fledged Non-equilibrium Green’s Function (NEGF) – Landauer model by introducing a spatial grid of N points and turning numbers …
Lecture 2B: Quantum Transport
Lecture 3A: Spin Transport
Objective: To extend the model from Lectures 1 and 2 to include electron spin. Every electron is an elementary “magnet” with two states having opposite magnetic moments. Usually this has no major …
Lecture 3B: Spin Transport
Lecture 4B: Energy Exchange and Maxwell’s Demon
Objective: To incorporate distributed energy exchange processes into the previous models from lectures 1 through 3 which are based on a “Landauer-like picture” where the Joule heating associated …
Lecture 5A: Correlations and Entanglement
Objective: To relate the one-electron picture used throughout these lectures to the more general but less tractable many-particle picture that underlies it. We introduce this new viewpoint using the …
Lecture 5B: Correlations and Entanglement
Nanoelectronics and the Meaning of Resistance
20 Aug 2008 | Courses | 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 …

Nano Carbon: From ballistic transistors to atomic drumheads
14 May 2008 | Online Presentations | Contributor(s): Paul L. McEuen
Carbon takes many forms, from precious diamonds to lowly graphite. Surprisingly, it is the latter that is the most prized by nano physicists. Graphene, a single layer of graphite, can serve as an …

Simulate Coulomb Blockade through Many-Body Calculations in a single and double quantum dot system
Nanoelectronic Modeling: Multimillion Atom Simulations, Transport, and HPC Scaling to 23,000 Processors
07 Mar 2008 | Online Presentations | Contributor(s): Gerhard Klimeck
Future field effect transistors will be on the same length scales as “esoteric” devices such as quantum dots, nanowires, ultra-scaled quantum wells, and resonant tunneling diodes. In those …
MCW07 A Quantum Open Systems Approach to Molecular-Scale Devices
25 Feb 2008 | Online Presentations | Contributor(s): Yongqiang Xue
Experimental advances in electrically and optically probing individual molecules have provided new insights into the behavior of single quantum objects and their interaction with the nanoenvironments …
MCW07 Physics of Contact Induced Current Asymmetry in Transport Through Molecules
25 Feb 2008 | Online Presentations | Contributor(s): Bhaskaran Muralidharan, Owen D. Miller, Neeti Kapur, Avik Ghosh, Supriyo Datta
We first outline the qualitatively different physics involved in the charging-induced current asymmetries in molecular conductors operating in the strongly coupled (weakly interacting) …
