In low-temperature resonant Raman experiments on MoSe_{2}-WSe_{2} heterobilayers, we identify a hybrid interlayer shear mode (HSM) with an energy close to the interlayer shear mode (SM) of the heterobilayers, but with a much broader, asymmetric lines

Here, the authors investigate excitonic transitions in mono- and multi-layer WSe2 and MoSe2 by time-resolved Faraday ellipticity (TRFE) with in-plane magnetic fields, and attribute the oscillatory TRFE signal in the multilayer samples to pseudospin q

In transition metal dichalcogenide monolayers, the spin and valley degrees of freedom are strongly coupled. Here, the authors engineer a WSe2/MoSe2 heterostructure in which inter-valley transitions of interlayer excitons exhibit a giant splitting and

Atomically thin transition metal dichalcogenides host excitons and trions, however higher-order states, although possible, are difficult to identify experimentally. Here, the authors perform polarization-resolved coherent spectroscopy to unveil the s

Electronic bandgap tuning in semiconductors enables key functionalities in solid-state devices. Here, the authors present a strategy to control the bandgap of atomically thin WS2 and WSe2semiconductors via manipulation of the surrounding dielectric e

The interplay between dark and bright excitons has a significant impact on the optical properties of semiconducting transition metal dichalcogenides. Here, the authors perform computational and experimental studies which unveil the microscopic origin

Monolayer transition metal dichalcogenides are promising materials for valleytronics applications. Here, the authors study WS2samples using photoluminescence spectroscopy and time-resolved Kerr-rotation measurements at low temperatures, gaining insig

Spin-orbit coupling underlies many important spintronic concepts, and is strongly influenced by crystal symmetry. Here, the authors demonstrate a strong enhancement of spin-orbit coupling in core/shell semiconductor nanowires induced by the large int

We report GaAs/AlGaAs nanowires in the one-dimensional (1D) quantum limit. The ultrathin wurtzite GaAs cores between 20-40\,nm induce large confinement energies of several tens of meV, allowing us to experimentally resolve up to four well separated s

As in many countries, the coronavirus pandemic is a major challenge facing labour law in Germany. On the one hand, the risk of infection in the workplace must be reduced as effectively as possible to prevent the pandemic from spreading. On the other
