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…
