Schematic illustrations of different facets of YbMnBi₂. (a) Same STM image with Fig. 1(c) in two-dimensional representation. (b) and (c) Height profiles along the blue solid line and red dashed line in (a), respectively. (d) Side view of the atomic structure of YbMnBi₂. (001) and (015) surface orientations are labeled. Blue, purple, yellow balls stand for Mn, Bi, Yb atoms, respectively. (e) Atomic configuration of YbMnBi₂ (015) surface. The orange rectangle represents the surface unit cell.
