Nanotubes beat metal wires, reach 10 GHz
From a UC Irvine press release, based on work published in Nano Letters: UC Irvine scientists have demonstrated for the first time that carbon nanotubes can route electrical signals on a chip faster than traditional copper or aluminum wires, at speeds of up to 10 GHz…Now that Burke’s team has developed both high-speed nanotube-interconnect technology and high-speed nanotube-transistor technology, they hope to integrate the two into an ultra-high-speed all-nanotube electronic circuit, faster than any existing semiconductor technology.

I’m half-way tempted to say facitiously, “Ho hum, YUAFNT*!”
By the way, just realized that nanodot moved from it’s old location and got a face lift. Here’s hoping it works well in it’s new location! WordPress is a good small scale CMS and has the potential to generate standards compliant markup. Good choice! The webmaster in me approves!**
Perhaps in honor of this, I’ve decided to start posting here with my real name. (My previous pseudonym here was “Mr. Farlops”)
* Yet Another Use For NanoTubes
** Kinda wished you could drop the antiquated use of layout tables though. But that’s a minor quibble.

Welcome, Pace Arko. I’ve enjoyed your earlier comments, and I think you and I talked by phone about ten years ago. How time flies. Hope to see you at our conference this fall? I thought this nanotube story was kind of cool because I hadn’t heard anyone propose an all-nanotube computer before…but I could have just missed an earlier story.

Wow, that is cool!

Wow, amazing work done here. It seems that nanotubes are quickly being proven to be on par or better than silicon in chips. I read another article about arrays of nanotubes on an integrated circuit. We appear to be just around the corner from the development of a simple computer (something like a 4 function calculator) made solely of nanotubes. Progress is happening much faster than expected if I’m not mistaken. This work is making me think that Intel/AMD will have to adjust their timelines for including nanotubes into mass produced processors (currently slated for after 2020). It now appears that we could see nanotubes start to creep their way in by the end of the decade. If you use the multi-core processor trend as an indicator, the chip companies are capable of turning on a dime when a competitor implements a new technology. Lets hope the competition between AMD and Intel drives rapid integration of this work into their product lines.

perfect! how did they solve the contact problem?

Dear Dr.Pace Arko,
It is an encouraging news that that nanotubes may become the conduting links.
How are the devices like LEDs,diodes and transistors inscribed in a chip. They are recommending only STM, MOCVD and MBE. STM , can be drafted only by synchronising several together. In either way they will be costlier than the Microelectronic chips.
Have you found by the earlier chemical reduction of long chain metal-organic radicals you can precipitate them on to chips by photo etching,engraving ,masking and printing.
Yours sincerely,

Dear DR Arko,
It is an encouraging news of dreaming a calculator with the conductance of Nanotubes. ?Have you found a method manufacturing on an integrated scale of devices with nanodots on a chip with condufting tubes to provide the path? Are you using the same Gallium ion etcvhing etc. there?
STM, MOCVD and MBE are the recommended ones? Several STMs should be put on a conveyor vbelt to synchronise mass manufacture.
