Just read an interesting little article on graphene transistors. I’d never even heard of them before, apparently it’s the stuff that’s in your pencil. Anyway, with a bit of work you can make amazing transistors with it.
…electrons move through graphene with almost no resistance, generating little heat. What’s more, graphene is itself a good thermal conductor, allowing heat to dissipate quickly. Because of these and other factors, graphene-based electronics could operate at much higher speeds. … de Heer says, “I believe we can do a terahertz…”

It is a fairly recent development in condensed matter physics, and it has been very actively studied ever since physicists learned how to peel a single layer of graphite, using a scotch tape (as ridiculous as it sounds), few years ago. Interestingly, electrons in graphene are described by massless Dirac equation: http://www.nature.com/nature/journal/v438/n7065/abs/nature04233.html
