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.
Drones are, in essence, flying autonomous vehicles. Pros and cons surrounding drones today might well foreshadow the debate over the development of self-driving cars. In the context of a strongly regulated aviation industry, "self-flying" drones pose a fresh challenge. How safe is it to fly drones in different environments? Should drones be required for visual line of sight – as are piloted airplanes? Join EE Times' Junko Yoshida as she moderates a panel of drone experts.
