Extended Data Fig. 2: Effect of twist angle and strain on moiré periodicity.
From: Strongly correlated electrons and hybrid excitons in a moiré heterostructure

a, Plot of the relation between twist angle and strain difference which gives same moiré periodicity (λmoiré), shown for λmoiré from 20 to 30 nm. b, Strain difference dependence of moiré periodicity for a fixed twist angle of 0.8°.
