Quantized charge pumping through a quantum dot by surface acoustic waves
J. Ebbecke, N. E. Fletcher, T. J. B. M. Janssen +4
We present a realization of quantized charge pumping. A lateral quantum dot is defined by metallic split gates in a GaAs/AlGaAs heterostructure. A surface acoustic wave whose wavel…
Interaction Effects at Crossings of Spin-Polarised One-Dimensional Subbands
A. C. Graham, K. J. Thomas, M. Pepper +3
We report conductance measurements of ballistic one-dimensional (1D) wires defined in GaAs/AlGaAs heterostructures in an in-plane magnetic field, B. When the Zeeman energy is equal…
Quantized charge transport through a static quantum dot using a surface acoustic wave
N. E. Fletcher, J. Ebbecke, T. J. B. M. Janssen +4
We present a detailed study of the surface acoustic wave mediated quantized transport of electrons through a split gate device containing an impurity potential defined quantum dot…
Induced currents, frozen charges and the quantum Hall effect breakdown
K. V. Kavokin, M. E. Portnoi, A. J. Matthews +4
Puzzling results obtained from torque magnetometry in the quantum Hall effect (QHE) regime are presented, and a theory is proposed for their explanation. Magnetic moment saturation…
Three Key Questions on Fractal Conductance Fluctuations: Dynamics, Quantization and Coherence
A. P. Micolich, R. P. Taylor, T. P. Martin +9
Recent investigations of fractal conductance fluctuations (FCF) in electron billiards reveal crucial discrepancies between experimental behavior and the semiclassical Landauer-Butt…
