Remote sensor response study in the regime of the microwave radiation-induced magnetoresistance oscillations
Tianyu Ye, Ramesh Mani, Werner Wegscheider
A concurrent remote sensing and magneto-transport study of the microwave excited two dimensional electron system (2DES) at liquid Helium temperatures has been carried out using a c…
Remotely sensed transport in microwave photoexcited GaAs/AlGaAs two-dimensional electron system
Tianyu Ye, Ramesh Mani, Werner Wegscheider
We demonstrate a strong correlation between the magnetoresistive and the concurrent microwave reflection from the microwave photo-excited GaAs/AlGaAs two-dimensional electron syste…
Scanning Gate Imaging of quantum point contacts and the origin of the 0.7 Anomaly
Andrea Iagallo, Nicola Paradiso, Stefano Roddaro +6
The origin of the anomalous transport feature appearing at conductance G \approx 0.7 x (2e2/h) in quasi-1D ballistic devices - the so-called 0.7 anomaly - represents a long standin…
Spin-orbit splitting and effective masses in p-type GaAs two-dimensional hole gases
Fabrizio Nichele, Atindra Nath Pal, Roland Winkler +4
We present magnetotransport measurements performed on two-dimensional hole gases embedded in carbon doped p-type GaAs/AlGaAs heterostructures grown on [001] oriented substrates. A…
Imaging the Conductance of Integer and Fractional Quantum Hall Edge States
Nikola Pascher, Clemens Rössler, Thomas Ihn +3
We measure the conductance of a quantum point contact (QPC) while the biased tip of a scanning probe microscope induces a depleted region in the electron gas underneath. At finite…
Suppression of bulk conductivity in InAs/GaSb broken gap composite quantum wells
Christophe Charpentier, Stefan Fält, Christian Reichl +6
The two-dimensional topological insulator state in InAs/GaSb quantum wells manifests itself by topologically protected helical edge channel transport relying on an insulating bulk.…
