Colloquium on Graphene Physics and Devices
22 Sep 2009 | | Contributor(s):: Joerg Appenzeller, Supriyo Datta, Mark Lundstrom
This short course introduces students to graphene as a fascinating research topic as well as to develop their skill in problem solving using the tools and techniques of electronics from the bottom up.

Nanostructured Electronic Devices: Percolation and Reliability
17 Sep 2009 | | 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...

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...

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...

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.
Physics of Nanoscale MOSFETs
26 Aug 2008 | | Contributor(s):: Mark Lundstrom
Transistor scaling has pushed channel lengths to the nanometer regime where traditional approaches to MOSFET device physics are less and less suitable This short course describes a way of understanding MOSFETs that is much more suitable than traditional approaches when the channel lengths are of...
Introduction: Nanoelectronics and the meaning of resistance
20 Aug 2008 | | Contributor(s):: Supriyo Datta
This lecture provides a brief overview of the five-day short course whose purpose is to introduce a unified viewpoint for a wide variety of nanoscale electronic devices of great interest for all kinds of applications including switching, energy conversion and sensing. Our objective, however, is...
Nanoelectronics and the Meaning of Resistance
The purpose of this series of lectures is to introduce the "bottom-up" approach to nanoelectronics using concrete examples. No prior knowledge of quantum mechanics or statistical mechanics is assumed; however, familiarity with matrix algebra will be helpful for some topics.Day 1: What and where...
Electronics From the Bottom Up: a view of conductance
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...
