TL;DR: The results pave the way for room-temperature polaritonic devices based on multiple-quantum-well van der Waals heterostructures, where polariton condensation and electrical polariton injection through the incorporation of graphene contacts may be realized.

TL;DR: It is shown that the EQE of WSe2 devices grows with temperature, with room temperature EQE reaching 5%, which is 250× more than the previous best performance of MoS2 and MoSe2 quantum wells in ambient conditions.

TL;DR: The authors excite valley-addressable polaritons in MoSe2 incorporated in a photonic microcavity to reveal the valley pseudospin retention and robust states demonstrated.

TL;DR: In this article, a 10-fold PL lifetime shortening was achieved, as a consequence of Purcell enhancement of the spontaneous emission rate of photoluminescence (PL).

TL;DR: Depending on the strength and anisotropy of the cavity confining potential and of the TE-TM induced splitting, the exciton-polariton emissions exhibit either spin-vortex-like patterns or linear polarization, in good agreement with theoretical modeling.
