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…
