Beginning with the general model for transport, we mathematically derive
expressions for the four thermoelectric transport coefficients:
(i) Electrical conductivity,
(ii) Seebeck coefficient...
Lecture 6: 3D Nets in a 3D World: Bulk Heterostructure Solar Cells
Lecture 6: An Introduction to Scattering
In this lecture, we show how the mean-free-path (mfp) is related to the
time between scattering events and briefly discuss how the scattering
time is related to underlying physical processes.

Lecture 7: The Boltzmann Transport Equation
17 Aug 2011 | Online Presentations | Contributor(s): Mark Lundstrom
Semi-classical 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...
