  3. McCoy Lecture: Nanodevices and Maxwell's Demon

    04 Oct 2006 | | Contributor(s):: Supriyo Datta

    This is a video taped live lecture covering roughly the same material as lecture 1 of "Concepts of Quantum Transport". Video only.

  4. CQT Lecture 4: Coulomb blockade and Fock space

    30 Nov 2006 | | Contributor(s):: Supriyo Datta

    Objective: To illustrate the limitations of the model described in Lectures 2, 3 and introduce a completely different approach based on the concept of Fock space. I believe this will be a key concept in the next stage of development of transport physics.

    30 Nov 2006 | | Contributor(s):: Supriyo Datta

    Objective: To extend the simple model from Lecture 2 into the full-blown model combines the NEGF (Non-Equilibrium Green Function) method with the Landauer approach.

  6. CQT Lecture 2: Electrical Resistance - A Simple Model

    30 Nov 2006 | | Contributor(s):: Supriyo Datta

    Objective:To introduce a simple quantitative model for describing current flow in nanoscalestructures and relate it to well-known large scale properties like Ohm’s Law.

  7. CQT Lecture 1: Nanodevices and Maxwell's Demon

    30 Nov 2006 | | Contributor(s):: Supriyo Datta

    Objective: To illustrate the subtle interplay of dynamics and thermodynamicsthat distinguishes transport physics.

  8. CQT Introduction

    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...
