I wonder if these will yield good overclocking results at the start if there's untapped potential.

It looks like just continuing development in the story. So my post just shows they are getting closer. Goody!

If we get many more developments I will ask a mod to combine the threads.



The graphene vs CNT fight is a good one. I can't wait to see who wins as it means more power for us. When we start folding on quantum computers there is nothing we can't do and cancer does not have a chance!

There's some literature available on this subject. If you consider that heat is handled by carbon much better than silicon, then it is likely they will. However in this scenario described in the article, the nanotubes are still deposited on silicon, so it's still a factor. But in terms of electromigration, I haven't signed up with any of the various science journals available with the information, so I don't know. If there is an improvement, it is likely that the lifespan of these chips will hold up much better to overclocking in terms of being able to apply more voltage over time. But I am speculating of course...

It has been mentioned before that graphene and carbon nanotubes are basically the same thing. CNTs are just that, graphene, rolled up in a tube. I'd say it's likely people actually refer to CNTs when they say graphene.

I don't reckon graphene would actually be a very good choice as it is a single-atom thick sheet of carbon. Wouldn't a graphene conductor have to be pretty wide (relatively) to allow for the same amount of power to flow through it as a CNT?

The news article I linked seems to show that there is a differentiation in the way simple graphene is used compared to the CNTs. That being said, it is likely that even though single layers can't manage the same amount of current as a tube, they will also likely not require as much power to work properly, either (relatively, I'm saying, as both schemes will probably use much less power than the current silicon configuration).

here it is again: http://newsroom.ucla.edu/portal/ucla/researchers-develop-scalable-method-236006.aspx

edit: I am speaking mostly to the fact that the grahpene, though not as developed in terms of commercialization (according to the evidence) in this case, is deposited on a substrate also consisting of graphene. The CNTs in the article are still using a silicon substrate. I honestly don't know the pro's and con's specifically, but on speculation alone, this will make a difference.
