Andrei and her team have finally spotted electrons in graphene getting together in the right way. To do it, the team suspended micrometer-sized bits of graphene to avoid interference from the underlying substrate. The researchers then used a special arrangement of electrodes to keep from shorting out their own measurements, they report online this week in Nature. They observed quasiparticles with 1/3 an electron's charge. In fact, Andrei says, the researchers saw the effect at higher temperatures and lower magnetic fields than are needed to see it in semiconductors, suggesting that the electrons in graphene interact especially strongly.
This is turning out to be such an amazing material, as amazing, if not more, than the high-Tc superconductors.
