Researchers
in the US have found yet another use for the "wonder material"
graphene. Instead of exploiting the material's exceptional ability as an
electrical conductor, the team has found a way to use graphene as an extremely
thin "tunnel barrier" to conduction. The team says that this new
application is particularly suited to developing spintronics – a relatively new
technology that exploits the spin of an electron as well as its charge.
