Perhaps you are not familiar with doping techniques that open the band gap in Graphene - in eetimes December the feature about IBM opening the band gap for Graphene's. We are clearly in new territory here with Graphene's however I see the functional use to far exceed the expatiations of nano tubes.

Texas Instruments made clear to me that their goal is to eventually reach the wafer scale in growing graphene monolayers--the same way silicon is grown today. However, it will be many years before anybody progress from growing millimeter-scale patches to achieving the kind of control necessary for wafer scale growth.

I don't agree GroovyGeek, I think this is the most exciting material that will eventuallu replace silicon in certain applications. Material properties are very unique. We just don't know yet all manufacturing issues...Kris

Theoretically is the key word... Mobility in nanoribbons is more like 100-200. Furthermore graphene has no bandgap so it makes an incredibly lousy switch. Many have given up on that particular application. Graphene is the new nanotube - the next great white hope that will go nowhere, at least as far as high performance CMOS replacement is concerned.

"Theoretically, graphene can achieve electron mobilities of 10,000-to-100,000 cm2/Vs." does it mean the graphene transistor will be 4 times faster than the normal CMOS transistors ?
