  7. Lecture 6: An Introduction to Scattering

    16 Aug 2011 | | Contributor(s):: Mark Lundstrom

    In this lecture, we show how the mean-free-path (mfp) is related to thetime between scattering events and briefly discuss how the scattering time is related to underlying physical processes.

  8. Lecture 6: Graphene PN Junctions

    22 Sep 2009 | | Contributor(s):: Mark Lundstrom

    Outline:IntroductionElectron optics in grapheneTransmission across NP junctionsConductance of PN and NN junctionsDiscussionSummary

  9. Lecture 7: Connection to the Bottom Up Approach

    23 Sep 2008 | | Contributor(s):: Mark Lundstrom

    While the previous lectures have been in the spirit of the bottom up approach, they did not follow the generic device model of Datta. In this lecture, the ballistic MOSFET theory will be formally derived from the generic model for a nano-device to show the connection explicitly.

    17 Aug 2011 | | Contributor(s):: Mark Lundstrom

    Semi-classical carrier transport is traditionally described by the Boltzmann Transport Equation (BTE). In this lecture, we present theBTE, show how it is solved, and relate it to the Landauer Approach usedin these lectures
