Lecture 2: Thresholds, Islands, and Fractals
0.0 out of 5 stars
04 Nov 2008 | Online Presentations | Contributor(s): Muhammad A. Alam
Three basic concepts of the percolation theory – namely, percolation threshold, cluster size distribution, and fractal dimension – are defined and methods to calculate them are illustrated via...

Lecture 3: Resistance-Ballistic to Diffusive
28 Jul 2011 | Online Presentations | Contributor(s): Mark Lundstrom
The resistance of a ballistic conductor and concepts, such as the quantum
contact resistance, are introduced and discussed. The results are then
generalized to treat transport all the way from...

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...
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: Connection to the Bottom Up Approach
23 Sep 2008 | Online Presentations | 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...

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...
