Energy-dependent tunnelling from few-electron dynamic quantum dots
M. R. Astley, M. Kataoka, C. J. B. Ford +6
We measure the electron escape-rate from surface-acoustic-wave dynamic quantum dots (QDs) through a tunnel barrier. Rate-equations are used to extract the tunnelling rates, which c…
Geometric Suppression of Single-Particle Energy Spacings in Quantum Antidots
L. C. Bassett, C. P. Michael, C. J. B. Ford +4
Quantum Antidot (AD) structures have remarkable properties in the integer quantum Hall regime, exhibiting Coulomb-blockade charging and the Kondo effect despite their open geometry…
Surface-acoustic-wave-driven luminescence from a lateral p-n junction
J. R. Gell, P. Atkinson, S. P. Bremner +9
The authors report surface-acoustic-wave-driven luminescence from a lateral p-n junction formed by molecular beam epitaxy regrowth of a modulation doped GaAs/AlGaAs quantum well on…
Pulse-induced acoustoelectric vibrations in surface-gated GaAs-based quantum devices
S. Rahman, T. M. Stace, H. P. Langtangen +2
We present the results of a numerical investigation which show the excitation of acoustoelectric modes of vibration in GaAs-based heterostructures due to sharp nano-second electric…
A numerical investigation of a piezoelectric surface acoustic wave interaction with a one-dimensional channel
S. Rahman, M. Kataoka, C. H. W. Barnes +1
We investigate the propagation of a piezoelectric surface acoustic wave (SAW) across a GaAs/AlGaAs heterostructure surface, on which there is fixed a metallic split-gat…
Surface Acoustic Wave Single-Electron Interferometry
Roberta Rodriquez, Daniel K. L. Oi, Crispin H. W. Barnes +3
We propose an experiment to observe interference of a single electron as it is transported along two parallel quasi-one-dimensional channels trapped in a single minimum of a travel…
