Temperature dependence of the visibility in an electronic Mach-Zehnder interferometer
Masayuki Hashisaka, Andreas Helzel, Shuji Nakamura +7
We performed the conductance and the shot noise measurements in an electronic Mach-Zehnder interferometer. The visibility of the interference is investigated as a function of the e…

Edge Channel Interference Controlled by Landau Level Filling
L. V. Litvin, A. Helzel, H. -P. Tranitz +2
We study the visibility of Aharonov-Bohm interference in an electronic Mach-Zehnder interferometer (MZI) in the integer quantum Hall regime. The visibility is controlled by the fil…

Nonlocal vortex motion in mesoscopic amorphous Nb0.7Ge0.3 structures
A. Helzel, I. Kokanovic, D. Babic +5
We study nonlocal vortex transport in mesoscopic amorphous Nb0.7Ge0.3 samples. A dc current I is passed through a wire connected via a perpendicular channel, of a length L= 2-5 um,…
