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…
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…
