Theoretical Analysis of Drag Resistance in Amorphous Thin Films Exhibiting Superconductor-Insulator-Transition
Yue Zou, Gil Refael, Jongsoo Yoon
The magnetical field tuned superconductor-insulator transition in amorphous thin films, e.g., Ta and InO, exhibits a range of yet unexplained curious phenomena, such as a putative…
Transport Phase Diagram of Homogeneously Disordered Superconducting Thin Films
Yize Li, Carlos L. Vicente, Jongsoo Yoon
We have constructed a phase diagram in temperature-magnetic field-disorder space for homogeneously disordered superconducting tantalum thin films. Phases are phenomenologically ide…
Evidence of spatial inhomogeneity near the onset of magnetically induced insulating state in superconducting thin films
C. L. Vicente, Yongguang Qin, Jongsoo Yoon
Non-monotonic differential resistance (dV/dI) is observed in magnetically induced insulating films which exhibit apparent superconductor-metal-insulator transitions in the low temp…
Non-thermal origin of nonlinear transport across magnetically induced superconductor-metal-insulator transition
Y. Seo, Y. Qin, C. L. Vicente +2
We have studied the effect of perpendicular magnetic fields and temperatures on the nonlinear electronic transport in amorphous Ta superconducting thin films. The films exhibit a m…
Magnetically Induced Metallic Phase in Superconducting Tantalum Films
Yongguang Qin, Carlos L. Vicente, Jongsoo Yoon
We have studied the electronic transport properties of homogeneously disordered superconducting tantalum thin films in magnetic fields. The films exhibit three distinct transport r…
Current-induced suppression of superconductivity in tantalum thin films at zero magnetic field
Yongho Seo, Yongguang Qin, Kyusang Choi +1
We report our findings on the mechanism of current-induced suppression of superconductivity in amorphous tantalum films as thin as 5nm under zero applied magnetic field. Our result…
