  • Strongly interacting interlayer excitons and the interplay between excitons and electronic states have recently been studied in moire superlattices. Here the authors study moire WS2/WSe2 heterobilayer with tuneable electron and exciton populations and find signatures of an excitonic Mott insulating state.

  • By combining large-scale first-principles GW-BSE calculations and micro-reflection spectroscopy, the nature of the exciton resonances in WSe2/WS2 moiré superlattices is identified, highlighting non-trivial exciton states and suggesting new ways of tuning many-body physics.
