Extended Data Fig. 7: Line cuts of trion signal in the Mott insulator and correlated interlayer exciton insulator.
From: Correlated interlayer exciton insulator in heterostructures of monolayer WSe2 and moiré WS2/WSe2

For the Mott insulator (E = 80 mV nm−1), the WSe2 monolayer does not have a trion state, while in the correlated interlayer exciton insulator state, the WSe2 monolayer does have a trion state (E = 0, −4, and −8 mV nm−1).
