Lecture 7: The Boltzmann Transport Equation
Online Presentations | 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

Lecture 5: Thermoelectric Effects - Mathematics
Online Presentations | 16 Aug 2011 | Contributor(s):: Mark Lundstrom
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.
