Direct observation of vortices in an array of holes at low temperature: temperature dependance and first visualization of localized superconductivity
Cecile Veauvy, Klaus Hasselbach, Dominique Mailly
A scanning micro superconducting quantum interference device (microSQUID) microscope is used to directly image vortices in a superconducting Al thin film. We observe the temperatur…
Micro-SQUID characteristics
K. Hasselbach, D. Mailly, J. R. Kirtley
We report on the dependence on field and temperature of the critical current of micro-SQUIDs: SQUIDs with diameters as small as 1 micron, using Dayem bridges as weak links. We mode…
Aharonov-Bohm cages in the GaAlAs/GaAs system
C. Naud, G. Faini, D. Mailly +5
Aharonov-Bohm oscillations have been observed in a lattice formed by a two dimensional rhombus tiling. This observation is in good agreement with a recent theoretical calculation o…
First observation of Aharonov-Bohm cages in 2-D normal metal networks
Cecile Naud, Giancarlo Faini, Dominique Mailly
We report on magnetoresistance transport measurements performed on a bipartite tiling of rhombus in the GaAs/GaAlAs system. We observe for the first time large amplitude osci…
The spectral conductance of a proximity superconductor and the re-entrance effect
H. Courtois, P. Charlat, Ph. Gandit +2
In a mesoscopic metal in proximity with a superconductor, the electronic conductance is enhanced in a very energy-sensitive way. In this paper, we discuss the spectral conductance…
Tunneling in very small GaAs MESFET
W. Poirier, D. Mailly, M. Sanquer
We study the transport through gated GaAS:Si wires of 0.5 micrometer length in the insulating regime and observe transport via elastic tunneling at very low temperature. We describ…
