Interactions Between Massless Particles May Lead To Speedy, Powerful Electronic Devices

Researchers have discovered novel electronic properties in two-dimensional sheets of carbon atoms called graphene that could one day be the heart of speedy and powerful electronic devices. The new findings, previously considered possible by physicists but only now being seen in the laboratory, show that electrons in graphene can interact strongly with each other. The physicists discovered that the fractional quantum Hall effect in graphene is even more robust than in standard semiconductors.
