Lecture 3A: Spin Transport
Online Presentations | 20 Aug 2008 | Contributor(s):: Supriyo Datta
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 effect on device operation except to increase the conductance by a factor of two.But it is now...

Lecture 4A: Energy Exchange and Maxwell's Demon
Online Presentations | 02 Sep 2008 | Contributor(s):: Supriyo Datta
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 with current flow occurs entirely in the two contacts.Although there is experimental evidence that...

Lecture 5A: Correlations and Entanglement
Online Presentations | 20 Aug 2008 | Contributor(s):: Supriyo Datta
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 example of Coulomb blockaded electronic devices that are difficult to model within the picture...

Logic Devices and Circuits on Carbon Nanotubes
Online Presentations | 05 Apr 2006 | Contributor(s):: Joerg Appenzeller
Over the last years carbon nanotubes (CNs) have attracted an increasing interest as building blocks for nano-electronics applications. Due to their unique properties enabling e.g. ballistic transport at room-temperature over several hundred nanometers, high performance CN field-effect transistors...
