Temperature induced shift in the pinch-off voltage of mesoscopic devices
A. E. Hansen, A. Kristensen, H. Bruus
Detailed experimental studies of the conductance of mesoscopic GaAs devices in the few-mode regime reveal a novel thermal effect: for temperatures up to at least 10 K the measured…

Temperature dependent deviations from ideal quantization of plateau conductances in GaAs quantum point contacts
A. E. Hansen, A. Kristensen, H. Bruus
We present detailed experimental studies of the temperature dependence of the plateau conductance of GaAs quantum point contacts in the temperature range from 0.3 K to 10 K. Due to…
