Lecture 2: Thresholds, Islands, and Fractals
Online Presentations | 04 Nov 2008 | 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 elementary examples. These three concepts will form the theoretical foundation for discussion in Lecture...

Lecture 1: Percolation in Electronic Devices
Online Presentations | 04 Nov 2008 | Contributor(s):: Muhammad A. Alam
Even a casual review of modern electronics quickly convinces everyone that randomness of geometrical parameters must play a key role in understanding the transport properties. Despite the diversity of these phenomena however, the concepts percolation theory provides a broad theoretical framework...

Lecture 7: Connection to the Bottom Up Approach
Online Presentations | 23 Sep 2008 | 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 derived from the generic model for a nano-device to show the connection explicitly.

Electronics From the Bottom Up: a view of conductance
Online Presentations | 17 Aug 2007 | Contributor(s):: Supriyo Datta
Resistance is one of the first concepts an electrical engineer learns, but things get interesting at the nanoscale. Experimentalists have found that no matter how short the resistor is, its resistance cannot drop below a fundamental lower limit. They also found that resistance increases in...
