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…
From mesoscopic magnetism to the anomalous 0.7 conductance plateau
Henrik Bruus, Vadim V. Cheianov, Karsten Flensberg
We present a simple phenomenological model which offers a unifying interpretation of the experimental observations on the 0.7 conductance anomaly of quantum point contacts. The mod…
Activated Behavior of the 0.7 2(e^2)/h Conductance Anomaly in Quantum Point Contacts
A. Kristensen, H. Bruus, A. Forchel +5
The 0.7 conductance anomaly in the quantized conductance of trench etched GaAs quantum point contacts is studied experimentally. The temperature dependence of the anomaly measured…
Localized plasmons in point contacts
Henrik Bruus, Karsten Flensberg
Using a hydrodynamic model of the electron fluid in a point contact geometry we show that localized plasmons are likely to exist near the constriction. We attempt to relate these p…
