Unexpected edge conduction in HgTe quantum wells under broken time reversal symmetry
Eric Yue Ma, M. Reyes Calvo, Jing Wang +16
The realization of quantum spin Hall (QSH) effect in HgTe quantum wells (QWs) is considered a milestone in the discovery of topological insulators. The QSH edge states are predicte…
Spatially resolved study of backscattering in the quantum spin Hall state
Markus König, Matthias Baenninger, Andrei G. F. Garcia +8
The discovery of the Quantum Spin Hall state, and topological insulators in general, has sparked strong experimental efforts. Transport studies of the Quantum Spin Hall state confi…
Colossal non-saturating linear magnetoresistance in two-dimensional electron systems at a GaAs/AlGaAs heterointerface
M. A. Aamir, Srijit Goswami, Matthias Baenninger +5
Engineering devices with a large electrical response to magnetic field is of fundamental importance for a range of applications such as magnetic field sensing and magnetic read-hea…
Evidence of gate-tunable topological excitations in two-dimensional electron systems
R. Koushik, Matthias Baenninger, Vijay Narayan +5
Topological defects are ubiquitous from solid state physics to cosmology, where they drive phase transitions by proliferating as domain walls, monopoles or vortices. As quantum exc…
Highly enhanced thermopower in two-dimensional electron systems at milliKelvin temperatures
Srijit Goswami, Christoph Siegert, Matthias Baenninger +4
We report experimental observation of an unexpectedly large thermopower in mesoscopic two-dimensional (2D) electron systems on GaAs/AlGaAs heterostructures at sub-Kelvin temperatur…
Magnetic Field Induced Instabilities in Localised Two-Dimensional Electron Systems
M. Baenninger, A. Ghosh, M. Pepper +3
We report density dependent instabilities in the localised regime of mesoscopic two-dimensional electron systems (2DES) with intermediate strength of background disorder. They are…
