Orientation of hole quantum Hall nematic phases in an out-of-plane electric field
A. F. Croxall, F. Sfigakis, J. Waldie +2
We present observations of an anisotropic resistance state at Landau level filling factor in a two-dimensional hole system (2DHS), which occurs for certain values of hole d…
A complete laboratory for transport studies of electron-hole interactions in GaAs/AlGaAs systems
Ugo Siciliani de Cumis, Joanna Waldie, Andrew F. Croxall +5
We present GaAs/AlGaAs double quantum well devices that can operate as both electron-hole (e-h) and hole-hole (h-h) bilayers, with separating barriers as narrow as 5 nm or 7.5 nm.…
Switching between attractive and repulsive Coulomb-interaction-mediated drag in an ambipolar GaAs/AlGaAs bilayer device
B. Zheng, A. F. Croxall, J. Waldie +5
We present measurements of Coulomb drag in an ambipolar GaAs/AlGaAs double quantum well structure that can be configured as both an electron-hole bilayer and a hole-hole bilayer, w…
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…
