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…
Interplay of Dirac nodes and Volkov-Pankratov surface states in compressively strained HgTe
David M. Mahler, Julian-Benedikt Mayer, Philipp Leubner +8
Preceded by the discovery of topological insulators, Dirac and Weyl semimetals have become a pivotal direction of research in contemporary condensed matter physics. While easily ac…
Quantum anomalous Hall effect in Mn doped HgTe quantum wells
A. Budewitz, K. Bendias, P. Leubner +5
Magnetotransport measurements are presented on paramagnetic (Hg,Mn)Te quantum wells (QWs) with an inverted band structure. Gate-voltage controlled density dependent measurements re…
Interplay of chiral and helical states in a Quantum Spin Hall Insulator lateral junction
M. R. Calvo, F. de Juan, R. Ilan +11
We study the electronic transport across an electrostatically-gated lateral junction in a HgTe quantum well, a canonical 2D topological insulator, with and without applied magnetic…
Strain Engineering of the Band Gap of HgTe Quantum Wells using Superlattice Virtual Substrates
Philipp Leubner, Lukas Lunczer, Christoph Brüne +2
The HgTe quantum well (QW) is a well-characterized two-dimensional topological insulator (2D-TI). Its band gap is relatively small (typically on the order of 10 meV), which restric…
High-temperature quantum Hall effect in finite gapped HgTe quantum wells
T. Khouri, M. Bendias, P. Leubner +6
We report on the observation of the quantum Hall effect at high temperatures in HgTe quantum wells with a finite band gap and a thickness below and above the critical thickness $d_…
