Energy spectrum of valence band in HgTe quantum wells on the way from a two to the three dimensional topological insulator
G. M. Minkov, O. E. Rut, A. A. Sherstobitov +3
The magnetic field, temperature dependence and the Hall effect have been measured in order to determine the energy spectrum of the valence band in HgTe quantum wells with the width…
Transport properties of a 1000-nm HgTe film: the interplay of surface and bulk carriers
M. L. Savchenko, D. A. Kozlov, N. N. Mikhailov +2
We report on systematic study of transport properties of a 1000-nm HgTe film. Unlike to thinner and strained HgTe films, which are known as high-quality three-dimensional (3D) topo…
Topological insulators based on HgTe
Z. D. Kvon, D. A. Kozlov, E. B. Olshanetsky +3
The most interesting experimental results obtained in studies of 2D and 3D topological insulators (TIs) based on HgTe quantum wells and films are reviewed. In the case of 2D TIs, t…
Impact ionization induced by terahertz radiation in HgTe quantum wells of critical thickness
S. Hubmann, G. V. Budkin, M. Urban +9
We report on the observation of terahertz (THz) radiation induced band-to-band impact ionization in \HgTe quantum well (QW) structures of critical thickness, which are characterize…
Terahertz Magnetospectroscopy of Cyclotron Resonances from Topological Surface States in Thick Films of CdHgTe
M. Otteneder, D. Sacré, I. Yahniuk +10
We present studies of the cyclotron resonance (CR) in thick CdHgTe films with different cadmium concentrations corresponding to inverted and normal band order, as well…
Anomalous Decay of Quantum Resistance Oscillations of Two Dimensional Helical Electrons in Magnetic Field
S. Abedi, S. A. Vitkalov, N. N. Mikhailov +1
Shubnikov de Haas resistance oscillations of highly mobile two dimensional helical electrons propagating on a conducting surface of strained HgTe 3D topological insulator are studi…
Photogalvanic probing of helical edge channels in 2D HgTe topological insulators
K. -M. Dantscher, D. A. Kozlov, M. T. Scherr +10
We report on the observation of a circular photogalvanic current excited by terahertz (THz) laser radiation in helical edge channels of HgTe-based 2D topological insulators (TIs).…
Persistence of two-dimensional topological insulator state in wide HgTe quantum well
E. B. Olshanetsky, Z. D. Kvon, G. M. Gusev +4
Our experimental studies of electron transport in wide (14 nm) HgTe quantum wells confirm persistence of a two-dimensional topological insulator state reported previously for narro…
Transport in disordered two-dimensional topological insulator
G. M. Gusev, Z. D. Kvon, O. A. Shegai +3
We study experimentally the transport properties of "inverted" semiconductor HgTe-based quantum well, which is related to the two-dimensional topological insulator, in diffusive tr…
