9. Similar stripe structure have also been observed in low-coverage SAMs of longer alkanethiols, and they could form as an intermediate phase before evolution of the dense √3 × √3 phase. See R. Yamada and K. Uosaki, Langmuir, 14, 855 (1998) and references therein.

13. Though only at considerably low (110 K) temperature, Kondoh and Nozoye found a similar 3×4 unit cell for a methylthiolate monolayer on Au(111), and suggested a dominant role of Au-S interactions therein (H. Kondoh and H. Nozoye, J. Phys. Chem. B., 103, 2585. (1999)). However, neither this interpretation nor the proposed clustering of sulfur atoms (into tetramers at each corner of the unit cell) is comparable to the points made in our present paper.
