Giant anomalous Josephson effect as a probe of spin texture in topological insulators
Niklas Hüttner, Andreas Costa, Leandro Tosi +9
Surface states of topological insulators feature chiral spin-momentum locking. When such states are used as weak link between two superconductors, their spin texture gives rise to…
Magnetic field-bias current interplay in HgTe-based three-terminal Josephson junctions
J. Thieme, W. Himmler, F. Dominguez +8
We investigate HgTe/Nb-based three-terminal Josephson junctions in T-shaped and X-shaped geometries and their critical current contours (CCCs). By decomposing the CCCs into the con…
Quantum Hall effect and current distribution in the 3D topological insulator HgTe
S. Hartl, L. Freund, M. Kühn +8
We study the quantum Hall effect (QHE) in the three-dimensional topological insulator HgTe, which features topological Dirac-type surface states in a bulk gap opened by strain. Des…
Two-dimensional topological Anderson insulator in a HgTe-based semimetal
D. A. Khudaiberdiev, Z. D. Kvon, M. S. Ryzhkov +3
We report the experimental observation of Anderson localization in two-dimensional (2D) electrons and holes in the bulk of HgTe quantum wells with a semimetallic spectrum and under…
Anomalous conductance steps in three-dimensional topological insulator HgTe-based quantum point contacts
Elisabeth Richter, Michael Barth, Dmitriy A. Kozlov +8
We explore electrical transport through a point contact in strained HgTe, a three-dimensional topological insulator. In the absence of a magnetic field , there is no quantizatio…
Roles of band gap and Kane electronic dispersion in the THz-frequency nonlinear optical response in HgCdTe
Davide Soranzio, Elsa Abreu, Sarah Houver +7
Materials with linear electronic dispersion often feature high carrier mobilities and unusually strong nonlinear optical interactions. In this work, we investigate the THz nonlinea…
Electron-hole scattering-induced temperature behaviour of HgTe-based semimetal quantum well
A. V. Snegirev, V. M. Kovalev, M. V. Entin +3
The semimetal quantum well (QW) based on HgTe structures exhibiting unusual transport properties at low temperature is examined experimentally. It demonstrates either a linear or q…
Spin Splitting and Disorder in HgTe-Based Massless Dirac Fermion Landau Levels
D. A. Kozlov, J. Ziegler, N. N. Mikhailov +2
An experimental study of Landau levels (LLs) in a system of two-dimensional massless Dirac fermions based on a critical thickness HgTe quantum well has been carried out. The magnet…
Two-dimensional semimetal in HgTe quantum well under hydrostatic pressure
V. A. Prudkoglyad, E. B. Olshanetsky, Z. D. Kvon +3
We report results of systematic measurements of charge transport properties of the 20.5nm wide HgTe-based quantum well in perpendicular magnetic field, performed under hydrostatic…
Linear magnetoresistance in HgTe quantum wells
G. M. Gusev, E. B Olshanetsky, Z. D. Kvon +2
We report magnetotransport measurements in a HgTe quantum well with an inverted band structure, which is expected to be a two-dimensional (2D) topological insulator. A small magnet…
