Superconductor -Insulator Transition in Quasi-One-Dimensional Nanowires
… a molecular templating technique. A well-defined superconductor-insulator transition (SIT) is observed in homogeneous wires with lengths less than ∼200 nm. The total normal state resistance of the wire is found to be the control parameter for this transition with the critical point occurring near …

Superconductor-insulator transition induced by electrostatic charging in high temperature superconductors.
… pressure oxygen sputtering system to study the superconductor-insulator transition by electrostatic charging. While backside gating using SrTiO3 as a dielectric induces only small TC shifts, a clear transition between superconducting and insulating behavior was realized in a 7 unit cell thick …

Reactive DC magnetron sputtering of ultrathin superconducting niobium nitride films
… and was the starting point for work on the superconductor-insulator transition.

Duality and strongly correlated systems in two dimensions
… (superuniversality) among quantum Hall plateau transitions to the emergence of a charge-vortex symmetry near the field-tuned superconductor-insulator transition in thin films to the appearance of “anomalous” metallic states which evade localization. These problems elude theoretical understanding …

Two-dimensional superconducting states near zero temperature quantum phase transitions
… we further investigate the mechanism for the superconductor to insulator transition at zero temperature. We study the destruction of superconductivity due to the application of sufficient magnetic field in 2D films of MoGe and InOx. Unlike previous works, which concentrated on four point …

Spin-Mediated Transport in Superconducting and Spin-Polarized Systems
… in the residual resistivity ratio as well as a transition from weakly-localized to half-metallic conduction as x→0. From measurements of the ordinary and anomalous Hall effects, the charge carrier concentration was found to increase, while the anomalous Hall coefficient decreased by nearly an …
