In physics, chemistry and materials science, percolation concerns the movement and filtering of fluids through porous materials. During the last three decades, percolation theory, an extensive mathematical model of percolation, has brought new understanding and techniques to a broad range of topics in physics, materials science as well as geography.

2009 NCN@Purdue Summer School: Electronics from the Bottom Up
09 Jul 2009 | | Contributor(s):: Supriyo Datta, Mark Lundstrom, Muhammad A. Alam, Joerg Appenzeller
The school will consist of two lectures in the morning on the Nanostructured Electronic Devices: Percolation and Reliability and an afternoon lecture on Graphene Physics and Devices. A hands on laboratory session will be available in the afternoons.
Nanostructured Electronic Devices: Percolation and Reliability
In this series of lectures introduces a simple theoretical framework for treating randomness and variability in emerging nanostructured electronic devices for wide ranging applications – all within an unified framework of spatial and temporal percolation. The problems considered involve...

Energy and Nanoscience A More Perfect Union
27 Mar 2009 | | Contributor(s):: Mark Ratner
Huge problems of energy and sustainability confront the science/engineering community, mankind, and our planet. The energy problem comes in many dimensions, including supply, demand, conservation, transportation, and storage. This overview will stress the nature of these problems, and offer a...
Lecture 2: Thresholds, Islands, and Fractals
out of 5 stars
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 1: Percolation in Electronic Devices
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...
