thank you @motti2, yes, there is lots of interesting research on graphene and carbon nanotubes...even at small conference like CMOSET which I am chairing there are over 25 talks devoted to this topic...but I doubt you will see a commercial device within 5 years and willing to bet my paycheck that this will not happen by 2017...any takers?

Iniewski, I suspect graphene transistor technology is advancing faster then generally comprehended, is my guess / observation. The main challenges, some making headway, are process integration issues that are less specific to the formation of reproducible graphene, than to what might damage semiconductor ( edge? ) properties, when forming dielectric isolation and electrical contacts in integrated circuit type processing. Despite these type of practical ( but important ) technical challenges, some of the better R&D groups are making steady but sure progress. Curiously, not directly related, is that practical RF and possibly power Carbon Nanotube transistors are being developed that surmount the hodge podge of poor R&D results prior. Key is that in vertical aligned forests of grwon nanotubes, is that simple overvolting of top contacted arrays burns off the metallic tubes that were so problematic for such a long time ( current burnoff in parallel of ALL metallic tubes forming a residual pure semiconducting carbon nanotube forest - hence capable of transistor operation quite easily ) I think the challenges to graphene transistor (process) integration are not to be dismissed, but the progress as indicated in journal publications is steady and very promising is my guess. Not perfect, but not discouraging in the least ( far faster than R&D of individual ?placed carbon nanotube transistors is my intuition )

Graphene has higher thermal conductivity than copper but it is not going to replace semiconductors, conductors and insulators as the first statement seem to imply...for one it doesn't have well controlled bandgap so how do you build transistors? Kris
