Many-particle effects in optical transitions from zero-mode Landau levels in HgTe quantum wells
S. S. Krishtopenko, A. M. Kadykov, S. Gebert +9
We report on the far-infrared magnetospectroscopy of HgTe quantum wells with inverted band ordering at different electron concentrations. We particularly focus on optical transitio…
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…
Temperature-induced topological phase transition in HgTe quantum wells
A. M. Kadykov, S. S. Krishtopenko, B. Jouault +9
We report a direct observation of temperature-induced topological phase transition between trivial and topological insulator in HgTe quantum well. By using a gated Hall bar device,…
Temperature-driven massless Kane fermions in HgCdTe crystals: verification of universal velocity and rest-mass description
F. Teppe, M. Marcinkiewicz, S. S. Krishtopenko +15
It has recently been shown that the electronic states in bulk gapless HgCdTe offer another realization of pseudo-relativistic three-dimensional particles in a condensed matter syst…
