The signature of a double quantum-dot structure in the I-V characteristics of a complex system
L. Bitton, D. Radovsky, A. Cohen +2
We demonstrate that by carefully analyzing the temperature dependent characteristics of the I-V measurements for a given complex system it is possible to determine whether it is co…
Localization transition on complex networks via spectral statistics
M. Sade, T. Kalisky, S. Havlin +1
The spectral statistics of complex networks are numerically studied. The features of the Anderson metal-insulator transition are found to be similar for a wide range of different n…
Transverse "resistance overshoot" in a Si/SiGe two-dimensional electron gas in the quantum Hall effect regime
I. Shlimak, V. Ginodman, A. B. Gerber +3
We investigate the peculiarities of the "overshoot" phenomena in the transverse Hall resistance R_{xy} in Si/SiGe. Near the low magnetic field end of the quantum Hall effect platea…
Magnetoresistance of mesoscopic granular ferromagnets
A. Y. Dokow H. Vilchik, A. Frydman
We have performed magnetoresistance (MR) measurements of granular ferromagnets having lateral dimensions smaller than 0.5 m and containing a small number of grains (down to abou…
