Extended Data Fig. 4: Supercell shape influencing modulation potential.

a, Illustration of an isosceles triangular supercell. The base length is fixed at 240 nm and sides are defined as the period in panel (b). b, The modulation potential measured from several isosceles triangular supercells. In regions where supercells are distorted by unintentional strain, equilateral triangles become isosceles triangles. In this case, the extracted potential (blue spheres) deviates from the theoretical prediction (solid curve). The vertical red dashed line corresponds to the period of 240 nm, that is an equilateral triangle. Error bars represent the root mean square error from the sinusoidal fitting to KPFM measurements.
