A transistor is a semiconductor device used to amplify and switch electronic signals. It is made of a solid piece of semiconductor material, with at least three terminals for connection to an external circuit. A voltage or current applied to one pair of the transistor's terminals changes the current flowing through another pair of terminals. Because the controlled (output) power can be much more than the controlling (input) power, the transistor provides amplification of a signal.More information on Transistor can be found here.

Lecture 2: Thresholds, Islands, and Fractals
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...

Lecture 7: Connection to the Bottom Up Approach
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.
Lecture 6: Quantum Transport in Nanoscale FETs
12 Sep 2008 | | Contributor(s):: Mark Lundstrom
The previous lessons developed an analytical (or almost analytical) theory of the nanoscale FET, but to properly treat all the details, rigorous computer simulations are necessary. This lecture presents quantum transport simulations that display the internal physics of nanoscale MOSFETs. We use...
