'Metal'-like transport in high-resistance, high aspect ratio two-dimensional electron gases
Dirk Backes, Richard Hall, Michael Pepper +3
We investigate the striking absence of strong localisation observed in mesoscopic two-dimensional electron gases (2DEGs) (Baenninger et al 2008 Phys. Rev. Lett. 100 1016805, Backes…
Cavity-enhanced coherent light scattering from a quantum dot
A. J. Bennett, J. P. Lee, D. J. P. Ellis +7
Resonant excitation of atoms and ions in macroscopic cavities has lead to exceptional control over quanta of light. Translating these advantages into the solid state with emitters…
The effect of split gate size on the electrostatic potential and 0.7 anomaly within one-dimensional quantum wires on a modulation doped GaAs/AlGaAs heterostructure
L. W. Smith, H. Al-Taie, A. A. J. Lesage +9
We study 95 split gates of different size on a single chip using a multiplexing technique. Each split gate defines a one-dimensional channel on a modulation-doped GaAs/AlGaAs heter…
Energy-Tunable Quantum Dot with Minimal Fine Structure Created by Using Simultaneous Electric and Magnetic Fields
M. A. Pooley, A. J. Bennett, R. M. Stevenson +3
The neutral biexciton cascade of single quantum dots is a promising source of entangled photon pairs. The character of the entangled state is determined by the energy difference be…
Ultrafast electrical control of a resonantly driven single photon source
Y. Cao, A. J. Bennett, D. J. P. Ellis +3
We demonstrate generation of a pulsed stream of electrically triggered single photons in resonance fluorescence, by applying high frequency electrical pulses to a single quantum do…
Single-photon superradiance from a quantum dot
P. Tighineanu, R. S. Daveau, T. B. Lehmann +4
We report on the observation of single-photon superradiance from an exciton in a semiconductor quantum dot. The confinement by the quantum dot is strong enough for it to mimic a tw…
Observation of geometry dependent conductivity in two-dimensional electron systems
Dirk Backes, Richard Hall, Michael Pepper +3
We report electrical conductivity measurements on a range of two-dimensional electron gases (2DEGs) of varying linear extent. Intriguingly, at low temperatures () and low ca…
Determining energy relaxation length scales in two-dimensional electron gases
Jordan Billiald, Dirk Backes, Jürgen König +3
We present measurements of the energy relaxation length scale in two-dimensional electron gases (2DEGs). A temperature gradient is established in the 2DEG by means of a heat…
Measurement and control of electron wave packets from a single-electron source
J. Waldie, P. See, V. Kashcheyevs +6
We report an experimental technique to measure and manipulate the arrival-time and energy distributions of electrons emitted from a semiconductor electron pump, operated as both a…
