Two-Dimensional Electron Gas in InGaAs/InAlAs Quantum Wells

E. Diez, Y. P. Chen, S. Avesque +6

We designed and performed low temperature DC transport characterization studies on two-dimensional electron gases confined in lattice-matched InGaAs/InAl…

Power law resistivity behavior in 2D superconductors across the magnetic-field tuned superconductor-insulator transition

G. Sambandamurthy, A. Johansson, E. Peled +3

We present the results of a systematic study of thin-films of amorphous indium-oxide near the superconductor-insulator transition. We show that the film's resistivity follows a sim…

Symmetries of the Resistance of Mesoscopic Samples in the Quantum Hall Regime

E. Peled, Y. Chen, E. Diez +4

The symmetry properties of the resistance of mesoscopic samples in the quantum Hall regime are investigated. In addition to the reciprocity relation, our samples obey new symmetrie…

Experimental evidence for a collective insulating state in two-dimensional superconductors

G. Sambandamurthy, L. W. Engel, A. Johansson +2

We present the results of an experimental study of the current-voltage characteristics in strong magnetic field () of disordered, superconducting, thin-films of amorphous Indium…

Near-Perfect Correlation of the Resistance Components of Mesoscopic Samples at the Quantum Hall Regime

E. Peled, D. Shahar, Y. Chen +3

We study the four-terminal resistance fluctuations of mesoscopic samples near the transition between the and the quantum Hall states. We observe near-perfect correlatio…
