Bandstructure in Nanoelectronics
01 Nov 2005 | | Contributor(s):: Gerhard Klimeck
This presentation will highlight, for nanoelectronic device examples, how the effective mass approximation breaks down and why the quantum mechanical nature of the atomically resolved material needs to be included in the device modeling. Atomistic bandstructure effects in resonant tunneling...

Nanoparticle Synthesis and Assembly for Biological Sensing
25 Oct 2005 | | Contributor(s):: Gil Lee
Nanoparticles have unique physical and chemical properties that make them very useful for biological and chemical sensing. For example, colloidal gold has been used as an optical transducer for antibody based sensing for over twenty years and is the basis for a many of the point-of-use diagnostic...

Semiconductor Interfaces at the Nanoscale
17 Oct 2005 | | Contributor(s):: David Janes
The trend in downscaling of electronic devices and the need to add functionalities such as sensing and nonvolatile memory to existing circuitry dictate that new approaches be developed for device structures and fabrication technologies. Various device technologies are being investigated,...

Plasmonic Nanophotonics: Coupling Light to Nanostructure via Plasmons
03 Oct 2005 | | 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...

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...

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...

Nanomaterials: Quantum Dots, Nanowires and Nanotubes
15 Jul 2005 | | Contributor(s):: Timothy D. Sands
What is a quantum dot? What is a nanowire? What is a nanotube? Why are these interesting and what are their potential applications? How are they made? This presentation is intended to begin to answer these questions while introducing some fundamental concepts such as wave-particle duality,...

Single Electron Switching with Nano-Electromechanical Systems and Applications in Ion Channel Transport
01 Nov 2004 | | Contributor(s):: Robert H. Blick
Taking classes in physics always starts with Newtonian mechanics. In reducing the size of the objects considered however the transition into the quantum mechanical regime has to occur. The 'mechanics' of quantum mechanics is best studied in nano-structured semiconductor systems often termed...

Visualization of and Educational Tool for Quantum Dots
15 Aug 2004 | | Contributor(s):: Aaron Christensen, Adrian Rios
Quantum dots (QDs) are confined structures made of metals and semiconductors that are capable of containing free electrons.The ability to visualize these small devices is advantageous in determining probable electron orbitals and in observing information not easily conceived in raw datasets.

Control of Exchange Interaction in a Double Dot System
05 Feb 2004 | | Contributor(s):: Mike Stopa
As Rolf Landauer observed in 1960, information is physical. As a consequence, the transport and processing of information must obey the laws of physics. It therefore makes sense to base the laws of information processing and computation on the laws of physics and in particular on quantum...

Quantum-dot Cellular Automata
24 Nov 2003 | | Contributor(s):: Craig S. Lent
The multiple challenges presented by the problem of scaling transistor sizes are all related to the fact that transistors encode binary information by the state of a current switch. What is required is a new paradigm, still capable of providing general purpose digital computation, but which can...
