Nano Letters features our work on the Cover of its January 2016 issue

Graphene forms helicoids, akin to the mathematical Riemann surface for log(z), naturally occurring as screw dislocations in graphite or anthracite. In the Nano Letters paper, we demonstrate that the miniscule pitch of such winding carbon ribbons endows them with largest magnetic inductance per volume, which surpasses any current technologies. If voltage is applied, electrical current must flow helically, producing near the center strong magnetic field orders of magnitude greater than that of planet Earth.
