Rather than meaning “superb conductivity”, superconductivity is a specific electronic state of matter in which the conductivity drops to zero at a certain critical temperature, and magnetic fields are “expelled” from the material. In conventional (low-temperature) superconductors, this is caused by formation of electron pairs (Cooper pairs) that behave as bosons. There is no established mechanism for unconventional (high-temperature) superconductivity.
In any case, the present study does not mean that graphene is a superconductor.
- StavrosK 9y agoConductivity drops to zero? Did you mean resistance?
- nine_k 9y agoGraphene does not appear to be a superconductor, but apparently the enhanced conductivity is due to electrons forming interesting structures which lower the scattering effects of the atomic lattice. It reminded me about Cooper pairs, hence the joke.
