Pseudo-relativistic fermions and topological states in zinc-blende semiconductors and their heterostructures (Habilitation thesis)
Sergey S. Krishtopenko
Tracing my scientific path from many-body physics in semiconductor nanostructures to topological quantum matter, this Habilitation à diriger des recherches (HDR) memoir presents on…
Electrostatic Control Enables Robust Helical Edge Channel Transport in III-V Quantum Spin Hall Insulators
Manuel Meyer, Tobias Fähndrich, Sebastian Schmid +12
Quantum spin Hall transport in InAs/GaInSb-based two-dimensional topological insulators can be limited by parasitic bulk and edge contributions. We demonstrate that these limitatio…
Electrically driven Rabi dynamics of magnetic-field-induced corner states in a two-dimensional topological insulator
D. V. Khomitsky, E. A. Lavrukhina, D. P. Krasavin +2
We study coherent electric manipulation of magnetic-field-induced localized states at a double kink of a helical edge in a HgTe/CdHgTe quantum well. An in-plane magnetic field open…
Resonant Dyakonov-Shur Magnetoplasmons in Graphene Terahertz Photodetectors
Juan A. Delgado-Notario, Cedric Bray, Elsa Perez-Martin +16
Graphene plasmons confine incident terahertz fields far below the diffraction limit and, when hosted by a gate-defined Fabry-Perot cavity, enable electrically tunable, frequency-se…
A topological field-effect memristor
Manuel Meyer, Selena Barragan, Sergey Krishtopenko +13
Overcoming the limitations of the von Neumann architecture requires new computational paradigms capable of solving complex problems efficiently. Quantum and neuromorphic computing…
Quantum spin Hall effect in III-V semiconductors at elevated temperatures: advancing topological electronics
Manuel Meyer, Jonas Baumbach, Sergey Krishtopenko +13
The quantum spin Hall effect (QSHE), a hallmark of topological insulators, enables dissipationless, spin-polarized edge transport and has been predicted in various two-dimensional…
