Graphene transistors promise 100GHz speeds

Graphene, single sheets of graphitic carbon, is exciting because it is a single atom thick and has remarkably high electron mobilities (100 times greater than silicon), making it ideally suited to atomic-scale, high-speed operation. Also, graphene's electrical properties can be controlled, switching it among conducting, semiconducting and electrically insulating forms. That means graphene-only (or, more likely, graphene-mostly) devices are, in principle, possible.

In this week's Science, researchers from IBM demonstrate graphene-based field effect transistors (FETs) that may operate at much higher speeds (100GHz) than Si FETs. Graphene layers were thermally grown on two-inch SiC wafers and the FETs were formed using standard Si fabrication techniques with HfO2 as the gate oxide. That's a rather significant point—the researchers actually created an entire wafer of these devices.

Old news is old. I wrote an article on graphene transistors probably two years ago now.

But go IBM, get that tech rolling. I'm going to make crazy guitar stuff with it.

Wow, Sorry Whir, I didnt know it was old "news" - I missed your article

[Whir]

Pft. I was just being grouchy. Let me see if I can find it...

DailyTech - The World's Smallest Transistor -- Thanks Again, Graphene

And I linked to an article that was written in 07 about it, too.

I should read the article though, just to keep up.

yeah, I read verns post the other day too and was thinking the same thing, thought I had read an article about this a couple years back, apparently I wasn't imagining things either.

either way, its more up to date, and still interesting to read, see how its progressing.

It's just nice to see that it IS progressing. What ever happened to the organic technology they were working on years ago? I haven't seen anything about it in recent memory.

graphene though is intriguing....the fact that anything that thin and small can be manufactured in a controlled way is always amazing to me.

( I'm waiting for the "how it's made" segment on this people! )

Funny. We read about this tech stuff, and it disappears and comes back in some other countries invention that they sell to us.
