10. Our images are calibrated against LEED data for the distance of 50.2 Å between two stripes, from which a 13.3-Å zigzag period is determined. The lattice constant a is taken to be 5.43 Å. See, for example, S. Miura, K. Kato, T. Ide and T. Ichinokawa, Surf. Sci. 191, 259 (1987) and Ref. 6. These calibrated values are fully consistent with the STM data. The magnitude of the uncertainty in lengths determined exclusively by STM is typically <10%.
11. Y. Yamamoto, Phys. Rev. B 50, 8534 (1994) has proposed another 16×2 model, which features trimers of Si, dimerization of adjacent atoms along a chain, rumpling of the surface, and no adatoms. Our data (Fig. 1) are inconsistent with his model.
