Practically all desirable ELECTRONIC properties of graphene disappear when scaled deeply. Mobility drops below Si, techniques for surface passivation and contacting are non existent. Let's remember that the much ballyhooed properties are for um-wide suspended ribbons of exfoliated graphene. CVD deposited materials are a long long way off from even approaching the record setting performance of exfoliated materials. Nevertheless the "wake me up when you are ready for TSMC" attitude is really short sighted. The problem with graphene is that people bend over backwards trying to make it look like Si (witness BisFET and other related proposals). The intriguing aspects of this work are that it demonstrates a creative use of graphene's unique properties.

I guess I need to learn about nonboolean logic and I don't. :)

As I said before, we are going to need some CMOS alternatives soon. Keep cranking guys...and wake me up when you are ready for TSMC!

Of course, the power, size, etc. will go down as these non-Boolean circuits are optimized. You can get all the details of the current state of their research at:

It sounds like these devices would use a fair amount of power to maintain a state... True?

Also, those structures are huge. Does all of this scale down to where CMOS is today?
