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…
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.…
Insulating state and giant non-local response in an InAs/GaSb quantum well in the quantum Hall regime
Fabrizio Nichele, Atindra Nath Pal, Patrick Pietsch +4
We present transport measurements performed in InAs/GaSb double quantum wells. At the electron-hole crossover tuned by a gate voltage, a strong increase in the longitudinal resisti…
