ECE 606: Principles of Semiconductor Devices
12 Nov 2008 | Courses | Contributor(s): Muhammad A. Alam
In the last 50 years, solid state devices like transistors have evolved from an interesting laboratory experiment to a technology with applications in all aspects of modern life. Making transistors is a complex process that requires unprecedented collaboration among material scientists, solid state physicists, chemists, numerical analysts, and software professionals. And yet, as you will see in part 1 of this course (first 5 weeks), that the basics of current flow though solid state …
Solar Cell Fundamentals
19 Aug 2011 | Courses | Contributor(s): Mark Lundstrom, J. L. Gray, Muhammad A. Alam
The modern solar cell was invented at Bell Labs in 1954 and is currently receiving renewed attention as a potential contribution to addressing the world's energy challenge. This set of five tutorials is an introduction to solar cell technology fundamentals. It begins with a broad overview of solar cells and continues with a discussion of carrier generation and recombination in silicon solar cells. The tutorials continue with an overview of solar cell modeling and …
ECE 695A Reliability Physics of Nanotransistors
17 Jan 2013 | Courses | Contributor(s): Muhammad Alam
This course will focus on the physics of reliability of small semiconductor devices. In traditional courses on device physics, the students learn how to compute current through a device when a voltage is applied.
Nanostructured Electronic Devices: Percolation and Reliability
17 Sep 2009 | Courses | Contributor(s): Muhammad A. Alam
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 stochastic defect generation in integrated circuits (i.e. reliability), percolative transport in carbon nanonets for flexible electronics and nanbio sensors, and neo-classical electron/hole diffusion in phase-segregated polymer solar cells, etc.

The electronic devices these days have become so small that the number of dopant atoms in the channel of a MOFET transistor, the number of oxide atoms in its gate dielectric, the number silicon- or metal crystals in nanocrystal Flash memory, the number of Nanowires in a flexible nanoNET transistor, the number of crystals in an poly-crystalline transistors, etc. are all finite, and countable. Moreover many devices like super-capacitors and organic solar cells depend on the randomness their morphology to enhance their performance. How should we think about electron transport through such random systems? The traditional approaches based on effective media theory, virtual crystal approximation, or Monte Carlo simulation are generally not very effective in describing such transport well. This short course introduces percolation theory to electrical engineers and device physicists as a powerful technique to handle such stochastically random transport problems of electronic devices.
