Localized Superconductivity in the Quantum-Critical Region around the Disorder-Driven Superconductor-Insulator Transition.
We investigate low-temperature transport properties of thin TiN superconducting films, which differ in the degree of disorder. In zero magnetic field, we find an extremely sharp separation between superconducting- and insulating phases, demonstrating a direct superconductor-insulator transition without an intermediate metallic phase. Temperature- and magnetic field behaviors of the resistance ...
