    • Both atomic and molecular forms of halogen may be generated from such electrochemical cells. The measurements of halogen desorption from Pt (used as anode in the cell) can be found, e.g. in R. Schennach, E. Bechtold, Surf. Sci. 380 (1997) 9.

    • There are a few differences in the terrace width distributions plotted in Fig. 7b. The probability on Br-terminated surface at both the small (<80 Å) and large (>250 Å) width ranges are noticeably higher than on the clean surface. This is probably an impurity-induced effect. Severe step-pinning and broadening of terrace width distribution have been observed on samples with visible impurities.

    • It is obvious that the system energy is reduced by forming Br-terminated Si(111)-1 × 1 from Si(111)-7 × 7 + Br (not just Si(111)-7 × 7). But a direct comparison of step energy between the clean and Br-covered surfaces is difficult. According to Refs. [8,9], a large miscut range for stable vicinal structure after saturation Br exposure implies either small step energy and step repulsion or extremely high surface energy for possible facets.
