Nanotech transistor from IBM to improve cell phone

I’ve done some recent blogging on nanotech transistors (this post is on the very subject of the post you’re reading) and it looks like IBM has something gearing up for market-ready to improve cell phone range and battery life.

From the second link:

Researchers at the company are using nanotechnology to build a future generation of wireless transceivers that are much more sensitive than the ones found in phones today. They’ll also be made with a less expensive material, according to IBM. The catch is that the new chips probably won’t make it into consumers’ hands for another five or ten years.

The scientists, sponsored by DARPA (the U.S. Defense Advanced Research Projects Agency), have built prototype transistors with the new material, called graphene. It is a form of graphite that consists of a single layer of carbon atoms arranged in a honeycomb pattern. Graphene’s structure allows electrons to travel through it very quickly and gives it greater efficiency than existing transceiver chip materials, said Yu-Ming Lin, a research staff member at IBM in Yorktown Heights, New York. The project is part of DARPA’s CERA (Carbon Electronics for radio-frequency applications) program.
