Extended Data Fig. 6: SLAP sample with h-BN spacer.
From: Switching graphitic polytypes in elastically coupled cavities
Optical images of (a) bilayer graphene, (b) h-BN spacer with circular cavities, and (c) the final stacked heterostructure (marked as S8). (d) AFM topography of the sample surface showing four circular cavities of varying diameters. (e) Corresponding current map of the same region, revealing moiré domain patterns confined within each cavity. (f–j) Current maps of a single cavity (marked with a light blue square in panels d, e), acquired under a vertical loading force of 100 nN, show the evolution and partial motion of domain walls upon scanning in various directions. (k–m) Optical images of another SLAP sample (marked as S5) with an h-BN spacer. (n) Current map of a region with two interconnected cavities, capturing multiple dislocation lines within the channel region. (o) Corresponding topography map.
