Multi-probe analysis to separate edge currents from bulk currents in quantum spin Hall insulators and to analyze their temperature dependence
S. Benlenqwanssa, S. S. Krishtopenko, M. Meyer +13
We present a multi-probe transport analysis that effectively separates bulk and edge currents in large Hall bar devices with standard geometries. Applied to transport measurements…
Lasing of Moiré Trapped MoSe/WSe Interlayer Excitons Coupled to a Nanocavity
Chenjiang Qian, Mirco Troue, Johannes Figueiredo +8
We report lasing of moiré trapped interlayer excitons (IXs) by integrating a pristine hBN-encapsulated MoSe/WSe heterobilayer into a high- () nanophotonic cavity…
5.0 m emitting Interband Cascade Lasers with Superlattice and Bulk AlGaAsSb Claddings
B. PetroviÄ, A. Bader, J. Nauschütz +5
We present a comparison between interband cascade lasers (ICLs) with a 6-stage active region emitting at 5 m with AlSb/InAs superlattice claddings and with bulk Al_0.85 Ga_0.15…
GaSb-based Interband Cascade Laser with hybrid superlattice plasmon-enhanced claddings
B. PetroviÄ, A. Bader, J. Nauschütz +5
We present an interband cascade laser (ICL) emitting at 5.2 μm consisting of an 8-stage active region and a hybrid cladding composed of outer plasmon-enhanced InAs_0.915 Sb_0.085…
Dirac Cones and Room Temperature Polariton Lasing Evidenced in an Organic Honeycomb Lattice
Simon Betzold, Johannes Düreth, Marco Dusel +6
Artificial one- and two-dimensional lattices have emerged as a powerful platform for the emulation of lattice Hamiltonians, the fundamental study of collective many-body effects, a…
A source of entangled photons based on a cavity-enhanced and strain-tuned GaAs quantum dot
Michele B. Rota, Tobias M. Krieger, Quirin Buchinger +21
A quantum-light source that delivers photons with a high brightness and a high degree of entanglement is fundamental for the development of efficient entanglement-based quantum-key…
