Electrically tunable stacking domains and ferroelectricity in moiré superlattices

Leaky exciton condensates in transition metal dichalcogenide moiré bilayers

“…This temperature could be enhanced in bilayers with larger twist angles or intercalated hBN spacers, both increasing exciton bandwidth [14,45]. Addition-ally, an external electric field might also modify the moiré symmetry [14] or its elastic reconstruction [89,90], allowing further in-situ tunability. Above T the two emission lines are split by ∼ 20t ∼ 4 meV and should be resolvable.…”
