Counterpropagating topological and quantum Hall edge channels
Saquib Shamim, Pragya Shekhar, Wouter Beugeling +7
The survival of the quantum spin Hall edge channels in presence of an external magnetic field has been a subject of experimental and theoretical research. The inversion of Landau l…
Emergent quantum Hall effects below mT in a two-dimensional topological insulator
Saquib Shamim, Wouter Beugeling, Jan Böttcher +7
The realization of the quantum spin Hall effect in HgTe quantum wells has led to the development of topological materials which, in combination with magnetism and superconductivity…
One-dimensional weak antilocalization and band Berry phases in HgTe wires
M. Mühlbauer, A. Budewitz, B. Büttner +5
We study the weak antilocalization (WAL) effect in the magnetoresistance of narrow HgTe wires fabricated in quantum wells (QWs) with normal and inverted band ordering. Measurements…
