Fig. 5 — Healing effect on a floating band surface state. a, b The experimental and simulated QPI patterns from Si defects respectively. The patterns show reduced QPI features compared to Fig. 4. Only a subset of Q₁, Q₁ + G_x pockets are prominent, while Q₂ counterparts are suppressed by the anisotropic defect potential. An energy dependent healing effect of the C_4v breaking is captured by the simulations. c, d The energy-scattering vector dispersions from experiment and calculation, respectively. The dispersions are taken along the diagonal line in a and b. From the comparison between a and b, c and d, we note that the simulations fit well to the measurements in a large energy range by considering the non-symmorphic effect
