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…
Experimental studies of the fractional quantum Hall effect in the first excited Landau level
W. Pan, J. S. Xia, H. L. Stormer +7
We present a spectrum of experimental data on the fractional quantum Hall effect (FQHE) states in the first excited Landau level, obtained in an ultrahigh mobility two-dimensional…
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…
Quantization of the diagonal resistance: Density gradients and the empirical resistance rule in a 2D system
W. Pan, J. S. Xia, H. L. Stormer +7
We have observed quantization of the diagonal resistance, R_xx, at the edges of several quantum Hall states. Each quantized R_xx value is close to the difference between the two ad…
