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 theory of magneto-transport in quantum dots: 3D-0D and 2D-0D tunnelling and selection rules for the angular momentum
B. Jouault, M. Boero, G. Faini +1
A study of magneto-transport through quantum dots is presented. The model allows to analyze tunnelling both from bulk-like contacts and from 2D accumulation layers. The fine featur…
Effect of the angular momentum on the magnitude of the current in magneto-tunnelling spectroscopy of quantum dots
B. Jouault, J. P. Holder, M. Boero +5
We present an experimental and theoretical study of electron tunnelling through quantum dots which focusses the attention on the amplitude of the current peaks as a function of mag…
