[Science Daily] Carbon Nanoribbons Could Make Smaller, Speedier Computer Chips

For the first time, a research team led by Hongjie Dai, the J. G. Jackson and C. J. Wood Professor of Chemistry, has made transistors called "field-effect transistors"—a critical component of computer chips—with graphene that can operate at room temperature. Graphene is a form of carbon derived from graphite. Other graphene transistors, made with wider nanoribbons or thin films, require much lower temperatures.


Quote:
David Goldhaber-Gordon, an assistant professor of physics at Stanford, proposed that graphene could supplement but not replace silicon, helping meet the demand for ever-smaller transistors for faster processing. "People need to realize this is not a promise; this is exploration, and we'll have a high payoff if this is successful," he said.

Dai said graphene could be a useful material for future electronics but does not think it will replace silicon anytime soon. "I would rather say this is motivation at the moment rather than proven fact," he said.

probably much more expensive than silicon, but we shall see

probably not much more than silicon... graphite is one of the cheapest materials in the world, and i would assume their processing techniques are rather inexpensive. it's a very simple material to work with; simply a loosely packed lattice of carbon atoms.

the next step for AMD chips? good god, i hope so, AMD could really use a backup plan right now for their AM3 socket line of chips (if it doesn't do as good as the AM2 socket, i mean)

Backup plan? This is the kind of technology which needs billions invested in and years of R&D - AMD aren't going to have a few scientists working on the side, they need whole departments.

And as good as the AM2 socket? Please say that was sarcasm...

i was meaning the processors, AM2 CPU's are selling like crazy b/c they are fairly cheap dual cores. by backup plan, i was meaning that they need to create a line of the 45nm process with nanoribbons for extra profit (R&D, etc.) you don't have to be so biased either, if you don't like AMD, then fine go post a thread in the "Rants and Raves" section of OCN, instead of spreading your hate in a thread, after someone comments something AMD should do to get better, and start gaining some revenue...

I'm not being biased, I had a 939 system and have just bought another one. AM2? No thanks.

Like I said, this is far too expensive and far away to be used as a backup plan - they'd have to ditch their existing fabs or reoutfit them with completely new technology, once they've developed how to make these chips efficiently and effectively. And before you have a go, same goes for Intel/VIA =/

Ad I know where the R&R section is Maybe you should go and post a rave about how great AM2 chips are? Obviously, every one agrees with you. One point - a X2 6000+ gets 22.5 seconds at SuperPi at 4ghz...E6600 gets 13 seconds at 4ghz. If your allowed to wander round making statements about how great AMD are doing with AM2, it's a bit hypocritical to say that I'm not allowed to point out the slight flaw in your argument

939 is outdated and over priced. And you bought another one? One sec let me LOLERSMITE you.

One point before I say anything else - no one is going to sig you because you insulted someone with l33t. Nice try though, your obviously extremely cool.

Seeing as I paid $100 in total for a new system (Opty 146, DFI SLI-DR, 1GB DDR600) I'm not complaining. Plus my 939 system was what got me into overclocking, so it's a trip down memory lane. Putting it under DiCE/SS should be good fun
