  6. Quantum and Thermal Effects in Nanoscale Devices

    Online Presentations | 18 Sep 2008 | Contributor(s):: Dragica Vasileska

    To investigate lattice heating within a Monte Carlo device simulation framework, we simultaneously solve the Boltzmann transport equation for the electrons, the 2D Poisson equation to get the self-consistent fields and the hydrodynamic equations for acoustic and optical phonons. The phonon...

  7. ECE 495N Lecture 7: Quantum Capacitance/Shrödinger's Equation

  8. Lecture 6: Quantum Transport in Nanoscale FETs

    Online Presentations | 12 Sep 2008 | Contributor(s):: Mark Lundstrom

    The previous lessons developed an analytical (or almost analytical) theory of the nanoscale FET, but to properly treat all the details, rigorous computer simulations are necessary. This lecture presents quantum transport simulations that display the internal physics of nanoscale MOSFETs. We use...

  10. 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...

    Online Presentations | 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...

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

    Online Presentations | 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...
