The Posible Future of Electronics Graphene

The Royal Swedish Academy of Sciences has awarded the Nobel Prize in Physics for 2010 to Andre Geim and Konstantin Novoselov, both of the University of Manchester, "for groundbreaking experiments regarding the two-dimensional material graphene."

Graphene is a form of carbon. As a material it is completely new -- not only the thinnest ever but also the strongest. As a conductor of electricity it performs as well as copper. As a conductor of heat it outperforms all other known materials. It is almost completely transparent, yet so dense that not even helium, the smallest gas atom, can pass through it. Carbon, the basis of all known life on earth, has surprised us once again.

When mixed into plastics, graphene can turn into conductors of electricity while making them more heat resistant and mechanically robust. Graphene transistors are predicted to be substantially faster than today's silicon transistors and result in more efficient computers

Some allotropes of carbon: a) diamond; b) graphite; c) lonsdaleite; d–f) fullerenes (C60, C540, C70); g) amorphous carbon; h) carbon nanotube.
