Localized superconductivity in the quantum-critical region of the disorder-driven superconductor-insulator transition in TiN thin films.

We investigate low-temperature transport properties of thin TiN superconducting films in the vicinity of the disorder-driven superconductor-insulator transition. In a zero magnetic field, we find an extremely sharp separation between superconducting and insulating phases, evidencing a direct superco... View More
