First Principles-based Atomistic and Mesoscale Modeling of Materials
Online Presentations | 01 Dec 2005 | Contributor(s):: Alejandro Strachan
This tutorial will describe some of the most powerful and widely used techniques for materials modeling including i) first principles quantum mechanics (QM), ii) large-scale molecular dynamics (MD) simulations and iii) mesoscale modeling, together with the strategies to bridge between them. These...

On the Reliability of Micro-Electronic Devices: An Introductory Lecture on Negative Bias Temperature Instability
Online Presentations | 28 Sep 2005 | Contributor(s):: Muhammad A. 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...

Quantum Dots
Online Presentations | 21 Jul 2005 | Contributor(s):: Gerhard Klimeck
Quantum Dots are man-made artificial atoms that confine electrons to a small space. As such, they have atomic-like behavior and enable the study of quantum mechanical effects on a length scale that is around 100 times larger than the pure atomic scale. Quantum dots offer application...

Parallel Computing for Realistic Nanoelectronic Simulations
Online Presentations | 12 Sep 2005 | Contributor(s):: Gerhard Klimeck
Typical modeling and simulation efforts directed towards the understanding of electron transport at the nanometer scale utilize single workstations as computational engines. Growing understanding of the involved physics and the need to model realistically extended devices increases the complexity...

Scientific Software Development
Online Presentations | 29 Jun 2005 | Contributor(s):: Clemens Heitzinger
The development of efficient scientific simulation codes poses a wide range of problems. How can we reduce the time spent in developing and debugging codes while still arriving at efficient programs? What happens when our codes must interact with existing tools? In recent years, higher-level...
