Surprises on the nanoscale: Plasmonic waves that travel backward and spin birefringence without magnetic fields
Online Presentations | 08 Jan 2007 | Contributor(s):: Daniel Neuhauser
As nanonphotonics and nanoelectronics are pushed down towards the molecular scale, interesting effects emerge. We discuss how birefringence (different propagation of two polarizations) is manifested and could be useful in the future for two systems: coherent plasmonic transport of near-field...

Technique for High Spatial Resolution, Focused Electrical Stimulation for Electrically Excitable Tissue
Online Presentations | 08 Aug 2006 | Contributor(s):: Matteo Mannino
Cochlear implant devices have made use of electrode pulses as a method of nerve fiber stimulation since their early conception. Electrode stimulation is limiting in both quality and consistency, and a new method is required if significant improvements to implant devices are to be made. By using a...

The Nano-MOSFET: A brief introduction
Online Presentations | 17 Aug 2007 | Contributor(s):: Mark Lundstrom
MOSFET channel lengths are now well below 100nm, and getting smaller, but MOSFETs are still modeled and understood much as they were 30 years ago. Seminal work in the 1960’s laid the foundation for our understanding of the MOSFET, but traditional approaches are based on concepts that lose...
