Q&A: What will 'wonder material' graphene give us?

I have to be honest with you, it takes a load of engineering in order to make graphene work as a transistor. Graphene doesn't have an energy gap.

In transistors nowadays it really is necessary to have this energy gap to have this on/off feature of a transistor, so you can't really do that with graphene right now.

Graphene is so far the most reliable material to replace silicon.

One area where graphene could be used soon in commercial products is in touchscreens. Screens with graphene will be extremely good in terms of conductivity, much more responsive to touch, and they will be much stronger and more durable as well because graphene is really resistant.

If they manage to put this in the manufacturing processes it will increase the speed a lot and when I say a lot I mean a thousand times. It will be really, really impressive.

How long until we see graphene in commercial use then?

There's still a lot of engineering to come so it's really difficult for a physicist to say.

I hope that in 10 years we will see something, when I'm talking about transistors. With touchscreens, maybe five years.
