Quantum Hall effect and zero plateau in bulk HgTe
M. L. Savchenko, D. A. Kozlov, S. S. Krishtopenko +4
The quantum Hall effect, which exhibits a number of unusual properties, is studied in a gated 1000-nm-thick HgTe film, nominally a three-dimensional system. A weak zero plateau of…
Optical realization of magneto-intersubband oscillations
M. L. Savchenko, A. A. Bykov, A. Shuvaev +3
We report on the optical realization of the magneto-intersubband oscillations that have been measured in the sub-terahertz transmittance of a GaAs quantum well with two subbands oc…
Optical Shubnikov - de Haas oscillations in 2D electron systems
M. L. Savchenko, J. Gospodaric, A. Shuvaev +6
We report on dynamic Shubnikov - de Haas (SdH) oscillations that are measured in the optical response, sub - terahertz transmittance of two-dimensional systems, and reveal two dist…
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…
Demonstration of high sensitivity of microwave-induced resistance oscillations to circular polarization
M. L. Savchenko, A. Shuvaev, I. A. Dmitriev +3
We demonstrate that long-debated immunity of microwave-induced resistance oscillations (MIRO) to the sense of circular polarization is not a generic property of this phenomenon in…
Observation of High Harmonics of the Cyclotron Resonance in Microwave Transmission of a High-Mobility Two-Dimensional Electron System
M. L. Savchenko, A. Shuvaev, I. A. Dmitriev +4
We report an observation of magnetooscillations of the microwave power transmitted through the high mobility two-dimensional electron system hosted by a GaAs quantum well. The osci…
Terahertz photoresistivity of a high-mobility 3D topological insulator based on a strained HgTe film
M. L. Savchenko, M. Otteneder, I. A. Dmitriev +3
We report on a detailed study of the terahertz (THz) photoresistivity in a strained HgTe three-dimensional topological insulator (3D TI) for all Fermi level positions: inside the c…
Weak antilocalization in partially relaxed 200-nm HgTe films
M. L. Savchenko, D. A. Kozlov, Z. D. Kvon +2
The anomalous magnetoresistance caused by the weak antilocalization (WAL) effects in 200-nm HgTe films is experimentally studied. The film is a high quality 3D topological insulato…
Two-dimension Dirac fermions system in CdHgTe quantum wells
M. L. Savchenko, D. A. Kozlov, Z. D. Kvon +3
We report on transport and capacitance spectroscopy study of two kinds of quantum wells, namely CdHgTe and CdHgTe with the thicknesses of 7.4 an…
Sign-alternating photoconductivity and magnetoresistance oscillations induced by terahertz radiation in HgTe quantum wells
M. Otteneder, I. A. Dmitriev, S. Candussio +7
We report on the observation of terahertz radiation induced photoconductivity and of terahertz analog of the microwave-induced resistance oscillations (MIRO) in HgTe-based quantum…
Probing quantum capacitance in a 3D topological insulator
D. A. Kozlov, D. Bauer, J. Ziegler +6
We measure the quantum capacitance and probe thus directly the electronic density of states of the high mobility, Dirac type of two-dimensional electron system, which forms on the…
