Possible effect of collective modes in zero magnetic field transport in an electron-hole bilayer
A. F. Croxall, K. Das Gupta, C. A. Nicoll +4
We report single layer resistivities of 2-dimensional electron and hole gases in an electron-hole bilayer with a 10nm barrier. In a regime where the interlayer interaction is stron…
Enhanced current quantization in high frequency electron pumps in a perpendicular magnetic field
S. J. Wright, M. D. Blumenthal, Godfrey Gumbs +8
We present experimental results of high frequency quantized charge pumping through a quantum dot formed by the electric field arising from applied voltages in a GaAs/AlGaAs system…
Magnetic Field Induced Instabilities in Localised Two-Dimensional Electron Systems
M. Baenninger, A. Ghosh, M. Pepper +3
We report density dependent instabilities in the localised regime of mesoscopic two-dimensional electron systems (2DES) with intermediate strength of background disorder. They are…
Patterned backgating using single-sided mask aligners: application to density-matched electron-hole bilayers
A. F. Croxall, K. Das Gupta, C. A. Nicoll +4
We report our work on fabricating lithographically aligned patterned backgates on thin (50-60m) \Roman{roman3}-\Roman{roman5} semiconductor samples using {\it single sided mask…
The effect of screening long-range Coulomb interactions on the metallic behavior in two-dimensional hole systems
L. H. Ho, W. R. Clarke, A. P. Micolich +6
We have developed a technique utilizing a double quantum well heterostructure that allows us to study the effect of a nearby ground-plane on the metallic behavior in a GaAs two-dim…
Post-selective two-photon interference from a continuous non-classical stream of photons emitted by a quantum dot
R. B. Patel, A. J. Bennett, K. Cooper +4
We report an electrically driven semiconductor single photon source capable of emitting photons with a coherence time of up to 400 ps under fixed bias. It is shown that increasing…
