Detection of Coulomb Charging around an Antidot
M. Kataoka, C. J. B. Ford, G. Faini +5
We have detected oscillations of the charge around a potential hill (antidot) in a two-dimensional electron gas as a function of a perpendicular magnetic field B. The field confine…
Detection of Coulomb Charging around an Antidot in the Quantum Hall Regime
M. Kataoka, C. J. B. Ford, G. Faini +5
We have detected oscillations of the charge around a potential hill (antidot) in a two-dimensional electron gas as a function of a large magnetic field B. The field confines electr…
Interaction Effects in a One-Dimensional Constriction
K. J. Thomas, J. T. Nicholls, N. J. Appleyard +5
We have investigated the transport properties of one-dimensional (1D) constrictions defined by split-gates in high quality GaAs/AlGaAs heterostructures. In addition to the usual qu…
Resonant Tunneling Spectroscopy of Interacting Localised States -- Observation of the Correlated Current Through Two Impurities
V. V. Kuznetsov, A. K. Savchenko, D. R. Mace +2
We study effects of Coulomb interactions between localised states in a potential barrier by measuring resonant-tunneling spectra with a small bias applied along the barrier. In the…
Possible Spin Polarization in a One-Dimensional Electron Gas
K. J. Thomas, J. T. Nicholls, M. Y. Simmons +3
In zero magnetic field, conductance measurements of clean one-dimensional (1D) constrictions defined in GaAs/AlGaAs heterostructures show twenty-six quantized ballistic plateaux, a…
Re-entrant resonant tunneling
V. V. Kuznetsov, A. K. Savchenko, M. E. Raikh +4
We study the effect of electron-electron interactions on the resonant-tunneling spectroscopy of the localized states in a barrier. Using a simple model of three localized states, w…
