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…
