Graphene Conducts Electricity Ten Times Better Than Expected

ananyo writes "Physicists have produced nanoribbons of graphene — the single-atom-thick carbon — that conduct electrons better than theory predicted even for the most idealized form of the material (abstract). The finding could help graphene realize its promise in high-end electronics, where researchers have long hoped it could outperform traditional materials such as silicon. In graphene, electrons can move faster than in any other material at room temperature. But techniques that cut sheets of graphene into the narrow ribbons needed to form wires of a nano-scale circuit leave ragged edges, which disrupt the electron flow. Now a team led by physicist Walt de Heer at the Georgia Institute of Technology in Atlanta has made ribbons that conduct electric charges for more than 10 micrometres without meeting resistance — 1,000 times farther than in typical graphene nanoribbons. The ribbons made by de Heer's team in fact conduct electrons ten times better than standard theories of electron transport they should, say the authors."

Re:We don't know that.

I can assure you it's not the same AC over and over because AC comments are throttled by IP address.

However, if slashdot dies because of this, it won't be because of Dice. It will be because like the dinosaurs, we couldn't adapt.

Why should we have to adapt to garbage? I don't think anyone would refuse to adapt to a new paint scheme, it's the fact that the new site is fundamentally and functionally broken by design. The fact that dice felt now was a good time to start forcing users to something so broken shows that they have a fundamental misunderstanding of what this place is about. It's not that the beta site is a little buggy, it's that it is completely broken.

At the very least they should have waited until commenting was at functional parity before revealing their hand but now it's too late, they have revealed the direction of things to come and it does not bode well for the future of the slashdot.org domain.
