Superconductivity in a disordered metal with Coulomb interactions
Svetlana V. Postolova, Alexey Yu. Mironov, Víctor Barrena +6
We study the electronic densities of states (DOS) of strongly disordered superconducting thin films of TiN. We find, using Scanning Tunneling Microscopy (STM) that the DOS decrease…
Disorder driven inhomogeneous phase in the 2D-superconducting film of titanium nitride
P. Kulkarni, S. Vieira, J. Rodrigo +3
Typically the superconducting phase weakens at several points with the increase in disorder before it is distroyed in the 2d-thin films. This may lead to an inhomogeneous supercond…
Superconducting phase transitions in ultrathin TiN films
T. I. Baturina, S. V. Postolova, A. Yu. Mironov +3
We investigate transition to the superconducting state in the ultrathin titanium nitride films on approach to superconductor-insulator transition. Building on the complete account…
Pseudogap in a thin film of a conventional superconductor
B. Sacepe, C. Chapelier, T. I. Baturina +3
A superconducting state is characterized by the gap in the electronic density of states which vanishes at the superconducting transition temperature Tc. It was discovered that in h…
Hyperactivated resistance in TiN films on the insulating side of the disorder-driven superconductor-insulator transition
T. I. Baturina, A. Yu. Mironov, V. M. Vinokur +2
We investigate the insulating phase that forms in a titanium nitride film in a close vicinity of the disorder-driven superconductor-insulator transition. In zero magnetic field the…
Localized Superconductivity in the Quantum-Critical Region of the Disorder-Driven Superconductor-Insulator Transition in TiN Thin Films
T. I. Baturina, A. Yu. Mironov, V. M. Vinokur +2
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…
Quantum Metallicity on the High-Field Side of the Superconductor-Insulator Transition
T. I. Baturina, C. Strunk, M. R. Baklanov +1
We investigate ultrathin superconducting TiN films, which are very close to the localization threshold. Perpendicular magnetic field drives the films from the superconducting to an…
Anomalous Behavior near T_c and Synchronization of Andreev Reflection in Two-Dimensional Arrays of SNS Junctions
T. I. Baturina, Yu. A. Tsaplin, A. E. Plotnikov +1
We have investigated low-temperature transport properties of two-dimensional arrays of superconductor--normal-metal--superconductor (SNS) junctions. It has been found that in two-d…
High-field side of Superconductor-Insulator Transition
Tatyana I. Baturina, D. R. Islamov, Z. D. Kvon +2
We report the experimental observation of a magnetic-field-tuned superconductor-insulator transition (SIT) in ultrathin TiN films. The low temperature transport properties of these…
