Superconductor-insulator transition in fcc-GeSb2Te4 at elevated pressures
Bar Hen, Samar Layek, Moshe Goldstein +8
We show that polycrystalline GeSb2Te4 in the fcc phase (f-GST), which is an insulator at low temperature at ambient pressure, becomes a superconductor at elevated pressures. Our st…
Proximity Effect in Superconducting-Ferromagnetic Granular Structures
Hadar Greener, Victor Shelukhin, Michael Karpovski +2
We examined the proximity effect in granular films made of Pb, a superconductor, and Ni, a ferromagnet, with various compositions. Slow decay of the critical temperature as a funct…
Resistivity Minimum in Granular Composites and Thin Metallic Films
A. Gerber, I. Kishon, D. Bartov +1
We analyze the temperature dependence of conductivity in thick granular ferromagnetic compounds NiSiO2 and in thin weakly coupled films of Fe, Ni and Py in vicinity of metal-insula…
Superconductivity in multiple phases of compressed GeSb2Te4
E. Greenberg, B. Hen, Samar Layek +10
Here we report the discovery of superconductivity in multiple phases of the compressed GeSb2Te4 (GST) phase change memory alloy, which has attracted considerable attention for the…
Dephasing measurements in InGaAs/AlInAs heterostructures: manifestations of spin-orbit and Zeeman interactions
L. H. Tzarfati, A. Aharony, O. Entin-Wohlman +4
We have measured weak antilocalization effects, universal conductance fluctuations, and Aharonov-Bohm oscillations in the two-dimensional electron gas formed in InGaAs/AlInAs heter…
Suppression of Coulomb blockade peaks by electronic correlations in InAs nanowires
R. Hevroni, V. Shelukhin, M. Karpovski +4
We performed electronic transport measurements on 1D InAs quantum wires. In sufficiently disordered wires, transport is dominated by Coulomb blockade, and the conductance can be we…
