Hybridized indirect excitons in MoS2/WS2 heterobilayers
Jonas Kiemle, Florian Sigger, Michael Lorke +5
Ensembles of indirect or interlayer excitons (IXs) are intriguing systems to explore classical and quantum phases of interacting bosonic ensembles. IXs are composite bosons that fe…
Tuning the Fröhlich exciton-phonon scattering in monolayer MoS2
Bastian Miller, Jessica Lindlau, Max Bommert +5
A direct band gap, remarkable light-matter coupling as well as strong spin-orbit and Coulomb interaction establish two-dimensional (2D) crystals of transition metal dichalcogenides…
Photo-induced anomalous Hall effect in the type-II Weyl-semimetal WTe2 at room-temperature
Paul Seifert, Florian Sigger, Jonas Kiemle +5
Using Hall photovoltage measurements, we demonstrate that an anomalous Hall-voltage can be induced in few layer WTe2 under circularly polarized light illumination. By applying a bi…
Switchable quantized conductance in topological insulators revealed by the Shockley-Ramo theorem
Paul Seifert, Marinus Kundinger, Gang Shi +5
Crystals with symmetry-protected topological order, such as topological insulators, promise coherent spin and charge transport phenomena even in the presence of disorder at room te…
