New silicon-germanium nanowires could lead to smaller, more powerful electronic devices (12/11/2009)

Currently chip manufacturers are facing great challenges in miniaturizing transistors, a semiconductor device commonly used to amplify or switch electronic signals. A recent study, published in the November 27 issue of Science, details how a team of researchers from UCLA, Purdue and IBM have successfully grown semiconducting nanowires made of silicon-germanium that could lead to a new generation of smaller, faster, and more powerful electronics many hope for in the industry. ...> Full Article

Engineers demonstrate nanotube wires operating at speed of commercial chips (2/16/2008)

Integrated circuits, such as the silicon chips inside all modern electronics, are only as good as their wiring, but copper conduits are approaching physical performance limitations as they get thinner. Chipmakers have hoped that carbon "nanotubes" would allow them to continue using thinner wiring as they pack more devices into chips, but no one had demonstrated nanotube wires working on a conventional silicon chip. In a paper published online today by the journal Nano Letters, electrical engineers at Stanford University and Toshiba report using nanotubes to wire a silicon chip operating at speeds comparable to those of commercially available processors and memory. ...> Full Article

Physicists pin down atomic spin for spintronics (9/13/2007)

Scientists who dream of shrinking computers to the nanoscale look to atomic spin as one possible building block for both processor and memory, yet setting the spin of an atom, let alone measuring it, has been a challenge. ...> Full Article
