Charge transport in two-dimensional conductors with hybrid three-component plasma
A. D. Levin, V. A. Chitta, Z. D. Kvon +2
Electron--hole plasma in two-dimensional systems has mainly been studied in two limiting cases: degenerate semimetals with parabolic bands and nondegenerate symmetric Dirac systems…
Interaction Induced Magnetotransport in a 2D Dirac-Heavy Hole Hybrid Band System
G. M. Gusev, A. D. Levin, V. A. Chitta +2
While electron-electron (e-e) interactions are known to influence resistivity in non-Galilean invariant two-dimensional (2D) systems, their effect on magnetotransport is not fully…
Magnetotransport in a 2D Hybrid Band System: Dirac and Heavy Hole Interplay
G. M. Gusev, A. D. Levin, V. A. Chitta +2
We investigate magnetoresistivity and the Hall effect in a 6.3 nm gapless HgTe quantum well - a two-dimensional hybrid band system featuring coexisting linear (Dirac-like) and para…
All-optical band structure reconstruction and onset of Landau quantization of Dirac fermions
Josef Riepl, Marc Aichner, Nikolai N. Mikhailov +6
The nature of relativistic electrons in solids depends on the precise shape of the underlying band structure. Prominently, symmetry-related mechanisms, such as the breaking of time…
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…
Interaction-controlled transport in a two-dimensional massless-massive Dirac system: Transition from degenerate to nondegenerate regimes
A. D. Levin, G. M. Gusev, F. G. G. Hernandez +4
The resistivity of two-dimensional (2D) metals generally exhibits insensitivity to electron-electron scattering. However, it's worth noting that Galilean invariance may not hold tr…
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…
Interaction dominated transport in 2D conductors: from degenerate to partially-degenerate regime
G. M. Gusev, A. D. Levin, E. B. Olshanetsky +4
In this study, we investigate the conductivity of a two-dimensional (2D) system in HgTe quantum well comprising two types of carriers with linear and quadratic spectra, respectivel…
Two-dimensional topological insulator state in double HgTe quantum well
G. M. Gusev, E. B. Olshanetsky, F. G. G. Hernandez +3
The two-dimensional topological insulator phase has been observed previously in single HgTe-based quantum wells with inverted subband ordering. In double quantum wells (DQWs), coup…
The resistance of 2D Topological insulator in the absence of the quantized transport
G. M. Gusev, Z. D. Kvon, E. B Olshanetsky +5
We report unconventional transport properties of HgTe wells with inverted band structure: the resistance does not show insulating behavior even when it is of the order of $10^2\tim…
