    Lecture 10: Case study-Near-equilibrium Transport in Graphene

    Near-equilibrium transport in graphene as an example of how to apply the concepts in lectures 1-8.

  2. ١٧‏/٠٨‏/٢٠١١

    Lecture 7: The Boltzmann Transport Equation

    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

    Lecture 9: Introduction to Phonon Transport

    This lecture is an introduction to phonon transport. Key similarities and differences between electron and phonon transport are discussed.

    Lecture 5: Thermoelectric Effects - Mathematics

    Beginning with the general model for transport, we mathematically deriveexpressions for the four thermoelectric transport coefficients:(i) Electrical conductivity,(ii) Seebeck coefficient (or "thermopower"),(iii) Peltier coefficient,(iv) Electronic heat conductivity.

    Lecture 6: An Introduction to Scattering

    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.

    Lecture 8: Measurements

    A brief introduction to commonly-used techniques, such as van der Pauw and Hall effect measurements.

  7. ٢٨‏/٠٧‏/٢٠١١

    Lecture 2: General Model for Transport

    Datta's model of a nanodevice is introduced as a general way of describing nanodevices as well, as bulk metals and semiconductors.

  8. ٢٨‏/٠٧‏/٢٠١١

    Lecture 3: Resistance-Ballistic to Diffusive

    The resistance of a ballistic conductor and concepts, such as the quantumcontact resistance, are introduced and discussed. The results are then generalized to treat transport all the way from the ballistic to diffusive regimes.

  9. ٢٨‏/٠٧‏/٢٠١١

    Lecture 4: Thermoelectric Effects-Physical Approach

    The effect of temperature gradients on current flow and how electrical currents produce heat currents are discussed.

    Lecture 1: Introduction to Near-equilibrium Transport

    A short overview of the topics to be discussed in the following nine lectures in this short course on near-equilibrium transport.
