  3. Lecture 1: Review of MOSFET Fundamentals

    26 Aug 2008 | | Contributor(s):: Mark Lundstrom

    A quick review of the traditional theory of the MOSFET along with a review of key device performance metrics. A short discussion of the limits of the traditional (drift-diffusion) approach and the meaning of ballistic transport is also included.

  4. Introduction: Nanoelectronics and the meaning of resistance

    20 Aug 2008 | | 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 kinds of applications including switching, energy conversion and sensing. Our objective, however, is...

  5. Lecture 1A: What and where is the resistance?

    20 Aug 2008 | | Contributor(s):: Supriyo Datta

    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 electrons hop in and out of the two contacts, labeled source and drain. This model is used to explain...

  7. Lecture 2A: Quantum Transport

    20 Aug 2008 | | Contributor(s):: Supriyo Datta

    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 like into (NxN) matrices like , with incoherent scattering introduced through . This model will be...

  9. Lecture 3A: Spin Transport

    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...

  11. Lecture 4B: Energy Exchange and Maxwell’s Demon

    20 Aug 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...

  12. Lecture 5A: Correlations and Entanglement

    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...
