Power law resistivity behavior in 2D superconductors across the magnetic field-tuned superconductor-insulator transition

We present the results of a systematic study of thin films of amorphous indium-oxide near the superconductor-insulator transition. We show that the film's resistivity follows a simple, well-defined, power law dependence on the perpendicular magnetic field. This dependence holds well into the insulating state. Our results suggest that a single mechanism governs the transport of our films in the superconducting as well as insulating phases.
