Why is graphene so special?
« on: 08/03/2012 18:48:01 »
ben.park asked the Naked Scientists:
   Hi,

There has been a lot of coverage in the news recently on the supermaterial graphene. What makes it so special and what are its possible applications? Could it be used to construct a space elevator for example?

Great show! Thanks

Ben Park
What do you think?

Wikipedia and many other sites on Google will tell you - but i wrote to Andre Geim and he sent me a copy of his article from The International journal of modern Physics

'Random Walk to graphene" which gives his Nobel lecture - I guess you could get it from the Nobel site too. This gives a pretty good overview of the whole thing.

The way it's layered make it very special. You can lift it off one atomic layer at a time quite easy, so you can get it very 'small'. and graphene leads electricity better than metal. Sometimes it's called 2-dimensional, referring to that the atoms are 'naked', one layer thick only which creates very special 'motions' if compared to the way a metal share its 'free electrons' in a 3-D environment, layer on layer. And you can manipulate that '2-D' layer by chemicals making into as small 'logic circuits' as we ever will be able to make classically.

Very cool - both to just sit down and write to the prizewinner himself, and of him to reply with a decent response.  I am gonna try that - I wouldn't have dreamt of just writing and asking a question to a nobel prize winner, but when I think of it mine is a very silly attitude.  Cheers
