Hybridization of topological surface states with a flat band
Sergey S. Krishtopenko, Mauro Antezza, Frédéric Teppe
We address the problem of hybridization between topological surface states and a non-topological flat bulk band. Our model, being a mixture of three-dimensional Bernevig-Hughes-Zha…
Unconventional Reentrant Quantum Hall Effect in a HgTe/CdHgTe Double Quantum Well
M. V. Yakunin, S. S. Krishtopenko, S. M. Podgornykh +7
We report on observation of an unconventional structure of the quantum Hall effect (QHE) in a -type HgTe/CdHgTe double quantum well (DQW) consisting of two HgTe lay…
Perspectives of HgTe Topological Insulators for Quantum Hall Metrology
Ivan Yahniuk, Sergey S. Krishtopenko, Grzegorz Grabecki +16
We report the studies of high-quality HgTe/(Cd,Hg)Te quantum wells (QWs) with a width close to the critical one , corresponding to the topological phase transition and graphen…
Terahertz detection of magnetic field-driven topological phase transition in HgTe-based transistors
A. Kadykov, F. Teppe, C. Consejo +12
We report on Terahertz detection by inverted band structure HgTe-based Field Effect Transistor up to room temperature. At low temperature, we show that nonlinearities of the transi…
The energy scale of Dirac electrons in Cd3As2
M. Hakl, S. Tchoumakov, I. Crassee +15
Cadmium arsenide (Cd3As2) has recently became conspicuous in solid-state physics due to several reports proposing that it hosts a pair of symmetry-protected 3D Dirac cones. Despite…
