Molecular Transport Structures: Elastic Scattering, Vibronic Effects and Beyond
13 Feb 2006 | | Contributor(s):: Mark Ratner, Abraham Nitzan, Misha Galperin
Current experimental efforts are clarifying quite beautifully the nature of charge transport in so-called molecular junctions, in which a single molecule provides the channel for current flow between two electrodes. The theoretical modeling of such structures is challenging, because of the...

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

Parallel Computing for Realistic Nanoelectronic Simulations
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...

Quantum Dots
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...

Scientific Software Development
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...
