Phonon mediated drag in double layer two dimensional electron systems
H. Noh, S. Zelakiewicz, T. J. Gramila +2
Experiments studying phonon mediated drag in the double layer two dimensional electron gas system are reported. Detailed measurements of the dependence of drag on temperature, laye…

Many-body correlations probed by plasmon-enhanced drag measurements in double quantum well structures
H. Noh, S. Zelakiewicz, X. G. Feng +3
Electron drag measurements of electron-electron scattering rates performed close to the Fermi temperature are reported. While evidence of an enhancement due to plasmons, as was rec…

Negative Electron Drag and Hole-Like behavior in the Integer Quantum Hall Regime
X. G. Feng, S. Zelakiewicz, H. Noh +4
Electron drag between two two-dimensional electron gases in magnetic fields has been observed with a polarity opposite that for zero field. This negative drag requires that the ele…
