First Ever Nanotube Transistors On A Circuit

Posted by timothy on from the waiting-for-productization dept.

btsdev writes "Researchers at the University of California at Berkeley and Stanford University have developed the first ever integrated silicon circuit with nanotube technology. According to the article on UC Berkeley's site, this brings researchers one step closer to developing memory chips with carbon nanotubes - chips that could hold approximately 10,000 times more data than those we have today."

    I guess this means the Ferengi do not have to abduct Seven of Nine after all.

  2. Heat and carbon nanotubes... by MajorDick · · Score: 5, Informative

    Ummmm. There is a pretty serious problem with heat dissapation and CARBON nanotubes Like this report shows

    Isnt this going to cause a pretty serious problem in integrating nanotube technology into electronics ?

      Did you even read the article you linked to? In order for that to happen, you need to fill a laundary list of rather specific criteria:

      1) Single walled nanotubes
      2) Presence of oxygen
      3) Temperatures in excess of 1,500 C
      4) Only intense light seems to effect it (photons are absorbed by the nanotubes directly)

      We can let #1 slide since I do not know if there is any specific requirement if nanotubes can (or must be) single or multi walled for use in electronics. Since there hasn't been any real development of nanotube electronics yet, I don't think anyone really knows. The linked article is about tool to analize nanotubes, not no much build electronic devices that incorperate them. It does make a good proof-of-concept though.

      #2 is easily remedied because the devices would be hermetically sealed in opaque packages. That also takes care of #4...

      And I don't think anyone will have to worry about the 1500 degree temperatures so far as electronics are concerned. At least nobody in the private sector...

      I mean damn, it's one thing to not RTFA, but you didn't even read your own sources!

      From TFA: Because extensive rearrangement of the carbon atoms occurs, the scientists estimate that the tubes reach temperatures of nearly 1,500 degrees Celsius.

      This doesn't happen *while* the nanotubes are at 1,500 C, the nanotubes heat up to 1,500 C as a result of the flash!

      You really *REALLY* should RTFA when chastising somebody else for not RTFA!

  3. Just like the teracubes by superpulpsicle · · Score: 5, Informative

    In 1995, there was alot of talk about a glass cube that can store a terabyte of data. This technology was expected to be around the market by 2005. Where is it now?

    Exactly. Like 90% of the great technical innovations they either don't make it for political reasons. Or heavily delayed for an eternity. Scary part is, Doom III will probably come out after this stuff.

    First off, congratulations to all involved on this achievement. They barely beat the research group I am a part of at Caltech, which is working on the same sort of thing. Our chip is in fab right now, returning in a month or so.

    Information on the Caltech research can be found here.
