Scientific Computing with Python

24 Oct 2004 | Online Presentations | Contributor(s): Eric Jones, Travis Oliphant

Python has emerged as an excellent choice for scientific computing because of its simple syntax, ease of use, and elegant multi-dimensional array arithmetic. Its interpreted evaluation allows it to serve as both the development language and the command line environment in which to explore data. …

Simple Theory of the Ballistic MOSFET

19 Oct 2005 | Online Presentations | Contributor(s): Mark Lundstrom

Silicon nanoelectronics has become silicon nanoelectronics, but we still analyze, design, and think about MOSFETs in more or less in the same way that we did 30 years ago. In this talk, I will describe a simple analysis of the ballistic MOSFET. No MOSFET is truly ballistic, but approaching this …

ECE 695s Lecture 4: Electromagnetic Properties of Molecules, Nano- and Microscopic Particles

07 Sep 2006 | Online Presentations | Contributor(s): Vladimir M. Shalaev

Piezoelectric Transducers: Strain Sensing and Energy Harvesting (and Frequency Tuning)

15 Jun 2007 | Online Presentations | Contributor(s): Toshikazu Nishida

Acoustic pressure or mechanical force sensing via piezoelectric coupling is closely related to the harvesting of electrical energy from acoustical and mechanical energy sources. In this talk, mesoscale and microscale piezoelectric transducers for acoustic and vibrational sensing and energy …

Geometry of Diffusion and the Performance Limits of Nanobiosensors

05 Dec 2006 | Online Presentations | Contributor(s): Muhammad Alam, Pradeep Ramachandran Nair

This presentation demonstrates how the classical diffusion-capture (D-C) model has improved sensor performance, since the D-C model is a "geometry of diffusion" rather than a "geometry of electrostatics." A scaling law based on D-C is also posited; the scaling law resolves many classical puzzles …

Electronic Transport in Semiconductors (Introductory Lecture)

26 Aug 2004 | Online Presentations | Contributor(s): Mark Lundstrom

Welcome to the ECE 656 Introductory lecture. The objective of the course is to develop a clear, physical understanding of charge carrier transport in bulk semiconductors and in small semiconductor devices.The emphasis is on transport physics and its consequences in a device context. The course does …

Nanoelectronic Architectures

28 Aug 2006 | Online Presentations | Contributor(s): Greg Snider

Nanoelectronic architectures at this point are necessarily speculative: We are still evaluating many different approaches to fabrication and are exploring unconventional devices made possible at the nano scale. This talk will start off with a review of some "classical" crossbar structures using …

PASI Lecture: Nanodevices and Maxwell's Demon, Part 1

13 Jun 2007 | Online Presentations | Contributor(s): Supriyo Datta

Pan American Advanced Study Institute (PASI) Lectures. This is part 1 of a video taped set of two one-hour live lectures covering roughly the same material as Lectures 1-3 of Concepts of Quantum Transport.

On the Reliability of Micro-Electronic Devices: An Introductory Lecture on Negative Bias Temperature Instability

03 Oct 2005 | Online Presentations | Contributor(s): Muhammad Alam

In 1930s Bell Labs scientists chose to focus on Siand Ge, rather than better known semiconductors like Ag2S and Cu2S, mostly because of their reliable performance. Their choice was rewarded with the invention of bipolar transistors several years later. In 1960s, scientists at Fairchild worked hard …

Plasmonic Nanophotonics: Coupling Light to Nanostructure via Plasmons

04 Oct 2005 | Online Presentations | Contributor(s): Vladimir M. Shalaev

The photon is the ultimate unit of information because it packages data in a signal of zero mass and has unmatched speed. The power of light is driving the photonicrevolution, and information technologies, which were formerly entirely electronic, are increasingly enlisting light to communicate and …
