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…
Anomalous Coulomb drag in electron-hole bilayers
A. F. Croxall, K. Das Gupta, C. A. Nicoll +5
We report Coulomb drag measurements on GaAs-AlGaAs electron-hole bilayers. The two layers are separated by a 10 or 25nm barrier. Below T1K we find two features that a Ferm…
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…
Cavity-enhanced radiative emission rate in a single-photon-emitting diode operating at 0.5 GHz
David J. P. Ellis, Anthony J. Bennett, Samuel J. Dewhurst +3
We report the observation of a Purcell enhancement in the electroluminescence decay rate of a single quantum dot, embedded in a microcavity light-emitting-diode structure. Lateral…
Evolution of entanglement within classical light states
R. Mark Stevenson, Andrew J. Hudson, Anthony J. Bennett +4
We investigate the evolution of quantum correlations over the lifetime of a multi-photon state. Measurements reveal time-dependent oscillations of the entanglement fidelity for pho…
