Lecture 2: Thresholds, Islands, and Fractals

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 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...
