Fig. 4: Atomic and electronic structure of zigzag domain walls.

a DW-2,8, b DW-1,4, and c DW-3,4. Red and blue dots in atomic structures denote the center site of the David-star cluster of left and right domains, respectively. The bottom panels are experimental STM images (scale bar = 2 nm). Insets are simulated STM images as same as Fig. 3. Green zigzag lines denote the domain edge. d Local DOS of DW-2,8, DW-1,4, and DW-3,4. Line colors in d correspond to the localized states at the clusters with the same color in atomic structures.
