Extended Data Fig. 8: Transport studies along the WTe2 crystal b-axis.
From: Switchable moiré potentials in ferroelectric WTe2/WSe2 superlattices
a, b, Electric field and filling factor dependence for the longitudinal resistance of angle-aligned bilayer Td-WTe2/monolayer H-WSe2 heterostructure at 10 K. The current is biased along the crystal b-axis of WTe2. The black arrows label the forward (a) and backward (b) electric field scan directions. Hysteretic electric field dependence corresponding to ferroelectric switching is observed. c, Filling factor dependent longitudinal resistance extracted from a (blue) and b (red) at E = 0.2 V/nm (the black dashed lines in a, b). They denote the two spontaneous polarization states P>0 and P<0. Moiré insulating states are observed only for P<0.
