Lecture 7: The Boltzmann Transport Equation
17 Aug 2011  Online Presentations  Contributor(s): Mark Lundstrom
Semiclassical carrier transport is traditionally described by the
Boltzmann Transport Equation (BTE). In this lecture, we present the
BTE, show how it is solved, and relate it to the Landauer Approach used
in 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
16 Aug 2011  Online Presentations  Contributor(s): Mark Lundstrom
Beginning with the general model for transport, we mathematically derive
expressions 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
16 Aug 2011  Online Presentations  Contributor(s): Mark Lundstrom
In this lecture, we show how the meanfreepath (mfp) is related to the
time between scattering events and briefly discuss how the scattering
time is related to underlying physical processes.
