Thanks so many guys for putting forward their opinions. As a third party of TI, Embest info&tech Co.,Ltd http://www.embedinfo.com/english/index.asp are able to expect a more bright future in business.

by far the most interesting though is apparently this latest practical tool to finally measure and even effect Andreev bound states (ABS)? http://www.sciencedaily.com/releases/2011/02/110214142348.htm "If you have two superconductors with a normal metal between, you can actually transport the superconductivity across the normal material via these bound states, even though the normal material doesn't have the electron pairing that the superconductors do," Mason said. ABS are extremely difficult to measure or to observe directly. Researchers can measure conduction and overall magnitude of a current, but have not been able to study individual ABS to understand the fundamental physics contributing to these unique states. Mason's group developed a method of isolating individual ABS by connecting superconducting probes to tiny, nanoscale flakes of graphene called quantum dots. ..." so assuming their superconducting probes where not this superconducting graphene but standard graphene then cant they also take even more advantage of the higher temperature inside your average silicon and make use of that heat to induce some super conductivity property in a hybrid core today... or did i misunderstand the concepts due the scientific ether/or thinking in these links? why cant we have both states and make use of them interacting.

we probably need a layman's guide on all this and what it mean's. but it seems there was lot's of talk about Superconductivity at 'room temperature' with graphene and using that in CPU design etc... http://torcuil.wordpress.com/2008/03/24/superconductivity-at-room-temperature-with-graphene/ stating room temperature CPU's always struck me as an odd goal as silicon CPU's have always run hotter inside, even if they only get warm by the time that generated heat reaches the outside packaging/lid however there are high-temperature uperconductors and talk of making Graphene: A Superconductor http://physics.aps.org/synopsis-for/10.1103/PhysRevLett.104.136803 http://techgenie.com/latest/the-creation-of-graphene-a-superconductor/

The temperature is way too high.

@R_Colin_Jhonson Could you please comment on the speed of Graphene transistor compared to the CMOS trasistor ?

Colombo: would it be possible to get a copy of that article that you are describing? kris.iniewski@gmail.com

We just want to clarify that the graphene growth referred to in this article was all performed in Prof. Rod Ruoff’s laboratory at UT Austin, in which we have been working with his group over the past 4 years in developing the process. Furthermore, the precise nature of the collaboration with IBM on this work was on the verification that the graphene grown at UT Austin by this method was indeed single crystal as described in our recently accepted joint article currently online on the Journal of the American Chemical Society website.

I agree Colin, sounds they will be able to grow graphene monolayers across the whole wafer one day but material science always takes much longer than people believe...I would give 10 years until graphene is commercially available...and it will help achieve Kurzweil's singularity ;-)...Kris
