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…

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…
