Designing Nanocomposite Materials for Solid-State Energy Conversion

28 Dec 2005 | Online Presentations | Contributor(s): Timothy D. Sands

New materials will be necessary to break through today's performance envelopes for solid-state energy conversion devices ranging from LED-based solid-state white lamps to thermoelectric devices for solid-state refrigeration and electric power generation. The combination of recent materials …

Nanotechnology-Enabled Direct Energy Conversion

05 Apr 2005 | Online Presentations | Contributor(s): Gang Chen

Energy transport in nanostructures differs significantly from macrostructures because of classical and quantum size effects on energy carriers such as on phonons, electrons, photons, and molecules. Nanoscale effects can be tailored to develop more efficient direct energy conversion technologies …

Silicon Spintronics

04 Jun 2008 | Online Presentations | Contributor(s): Ian Appelbaum

"Electronics" uses our ability to control electrons with electric fields via interaction with their fundamental charge. Because we can manipulate the electric fields within semiconductors, they are the basis for microelectronics, and silicon (Si) is the most widely-used semiconductor for …

Nanoelectronic Scaling Tradeoffs: What does Physics Have to Say?

12 Apr 2004 | Online Presentations | Contributor(s): Victor Zhirnov

Beyond CMOS, several completely new approaches to information-processing and data-storage technologies and architectures are emerging to address the timeframe beyond the current SIA International Technology Roadmap for Semiconductors (ITRS). A wide range of new ideas have been proposed for …

Digital Electronics: Fundamental Limits and Future Prospects

13 Apr 2004 | Online Presentations | Contributor(s): Konstantin K. Likharev

I will review some old and some recent work on the fundamental (and not so fundamental) limits imposed by physics of electron devices on their density and power consumption.

Quantum-dot Cellular Automata

12 Apr 2004 | Online Presentations | 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 be …
