Extended Data Fig. 1: Optical image of the device and STM topography of WSe2/hBN boundary.
From: Correlation-driven topological phases in magic-angle twisted bilayer graphene

a, Optical image of the device. The blue dashed line indicates the region with twisted bilayer graphene (TBG). b, STM topography of a WSe2 boundary underneath twisted bilayer graphene (Vbias = −400 mV, I = 20 pA). c, Linecut along the yellow dashed line in b. The height difference is around 0.8 nm, which matches the monolayer WSe2 thickness. Small ripples originate from the moiré pattern.
