Honored and grateful to be named on the @clarivateag.bsky.social #HighlyCited2025list. Big thank you to students, postdocs and collaborators as well as everybody who cited our papers and supported our work!

Big thank you to the group and collaborators: Jamie M. Fitzgerald and Ermin Malic for theoretical modeling; Takashi Taniguchi and Kenji Watanabe from NIMS Japan as well as @erc.europa.eu @snsf.ch and @ITN_2Exciting, financed by the EU and coordinated by @thomasheine.bsky.social.

The Q factor is still on the low side due to the presence of graphene electrodes but they allow us electrical tuning of the cavity coupling. Most surprisingly, we see a simultaneous enhancement of BOTH emission intensity and lifetime.

We have published a new paper in @natnano.nature.com by @EdoardoLopriore @FedeleTagarelli et al. We have integrated vdW heterostructures hosting interlayer excitons with a monolithic Fabry–Perot cavity. @EPFLEngineering @materials-epfl.bsky.social

Not surprised at all.
