Taming Light and Electrons with Metamaterials
11 Jul 2011 | Online Presentations | Contributor(s): Nader Engheta
In recent years, in my group we have been working on various aspects of metamaterials and plasmonic nano-optics. We have introduced and been developing the concept of "metatronics", i.e. metamaterial-inspired optical nanocircuitry, in which the three fields of "electronics", "photonics" and …

Putting the Electron’s Spin to Work
14 Apr 2011 | Online Presentations | Contributor(s): Daniel Ralph
I will discuss recent progress in experimental techniques to control the orientations of nanoscale magnetic moments and electron spins, and to use these new means of control for applications. One powerful new capability arises from the fact that thin magnetic layers can act as filters for spins.

Quantum Dots
21 Jul 2005 | Online Presentations | 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 opportunities …
