Nanowires grown at the National Institute of Standards and Technology (NIST) have a mechanical “quality factor” at least 10 times higher than reported values for other nanoscale devices such as carbon nanotubes, and comparable to that of commercial quartz crystals.

Chemical vapor deposition grown carbon nanotubes for interconnect technology

harminka — Fri, 23 Nov 2007 11:22:20 -0600

Computers and electronic devices of the future will utilise technologies not currently available. An example of such a technology is the use of carbon nanotubes as interconnects for computer chips. This is now a step closer to reality with some new work from nanotechnology researchers within the Materials Ireland Polymer Research Centre at Trinity College Dublin.

Carbon nanotubes to be replaced by MoSIx nanowires

Carbon nanotubes have long been touted as the wonder material of the future. Applications cited for carbon nanotubes range from super fast computers and ultra small electronics through to materials that are lightweight yet super strong and tougher than diamond.

NIST demos industrial-grade nanowire device fabrication

harminka — Sun, 28 Oct 2007 16:01:20 -0500

In the growing catalog of nanoscale technologies, nanowires—tiny rows of conductor or semiconductor atoms—have attracted a great deal of interest for their potential to build unique atomic-scale electronics. But before you can buy some at your local Nano Depot, manufacturers will need efficient, reliable methods to build them in quantity.
