The news of the first working experimental carbon nanotube computer was published in Nature (the journal) Sept. 25, 2103. Nature lists the authors as Professor Subhasish Mitra, Max M. Shulaker (Stanford) et al.. Other fine sources on this breakthrough in computing and transistor technology can be found in the BBC News and the Wall Street Journal. Oddly, the Examiner has not posted a story on the carbon nanotube computer named ‘Cedric’ (until this one)? Carbon nanotube computers “have been previously created” but Cedric provides correct solutions/responses to user queries – something not done until now.
To those in ‘geekland’ Cedric is a “Turing complete computer”. Although it is sometimes a bit of a joke to call something “Turing complete”. The carbon nanotube computer is something that has been in experimental development since 1998. But its theoretical development (carbon nanotube chips) has been traced back to research at Harvard in 2000. But NASA’s Ames Research may have been ahead on this track having posted their research on vertically integrated carbon nanotube interconnects in 2003. High temperatures are apparently required to grow or manufacture the needed carbon nanotubes per work at Rutgers.
And in 2009 MIT did some breakthrough work on manufacturing carbon nanotubes at low temperatures. Dr. Mitra received two federal research grants in August 2007 and September 2007 for “carbon nanotube (field-effect) transistors” and a fabric of same. The significance of his work may be indicated by the size of the combined awards at over $1.2 million. Dr. Mitra has received many other significant honors for his research in a wide variety of fields. Breakthrough research work mostly goes through many stages. The latest research and development work for this breakthrough carbon nanotube computer should also be worthy of awards for Mitra, Shulaker and the working group.
The “first stage” working experimental carbon nanotube computer could be eligible for at least two reasons: it is a working non-silicon based computer and it could be a breakthrough on Moore’s Law. NASA discussed this potential Moore’s Law breakthrough in their previously mentioned 2003 paper. The carbon nanotube transistors used in the computer are ‘thinner than a human hair – but still larger than today’s silicon chips’. And that means it’s still an experimental computer, of sorts.
