Anomalous Interlayer Exciton Diffusion in WS <sub>2</sub> /WSe <sub>2</sub> Moiré Heterostructure Open
Stacking van der Waals crystals allows for the on-demand creation of a periodic potential landscape to tailor the transport of quasiparticle excitations. We investigate the diffusion of photoexcited electron-hole pairs, or excitons, at the…

Phason-mediated interlayer exciton diffusion in WS2/WSe2 moiré heterostructure Open
Moiré potentials in two-dimensional materials have been proven to be of fundamental importance to fully understand the electronic structure of van der Waals heterostructures, from superconductivity to correlated excitonic states. However, …

Correlated insulator of excitons in WSe2/WS2 moiré superlattices Open
A panoply of unconventional electronic states has been observed in moiré superlattices. Engineering similar bosonic phases remains, however, largely unexplored. We report the observation of a bosonic correlated insulator in WSe2/WS2 moiré …
