One advantage of van der Waals materials is the ability to combine different materials in layers to form new heterostructures. Here, the authors investigate heterostructures of CrBr3 and MoSe2, and find that the ferromagnetism of CrBr3 enhances the v

Here, the authors report the creation of trion-polaritons in monolayer MoSe2 in an open microcavity exhibiting strong nonlinear interactions, one order of magnitude bigger than those observed for exciton polaritons in GaAs.

The authors present electroluminescence measurements of light-emitting devices based on van der Waals heterostructures, and observe a lower than expected threshold voltage for intralayer electroluminescence, attributed to non-radiative Auger-type rec

The unique valley and spin texture of atomically thin transition metal dichalcogenides (TMDs) allows the observation of the valley Zeeman effect for neutral and charged excitons. Here, the authors unveil the underlying physics of the magneto-optical

The short exciton life time in atomically thin transition metal dichalcogenides poses limitations to efficient control of the valley pseudospin and coherence. Here, the authors manipulate the exciton coherence in a WSe2 monolayer embedded in an optic

Precise control of the relative orientation of two two-dimensional layers enables reproducible fabrication of heterostructure devices. Here, the authors show that graphene rotates towards the crystallographic direction of a boron-nitride substrate du

We have investigated the optical properties of strained MoSe2 monolayer bubbles at low temperature. We have observed a red-shift of the exciton and trion emissions, a reduction of the trion binding energy and an enhancement of the valley g-factors.
