    • To accurately determine heights, after data acquisition, molecules were swept away by scanning at high loads. In such a way, any existing substrate step was visible and considered for the final height calculation of all the phases.

    • The length of the Cn molecules is estimated by assuming bond angles of 110° for both the Au-S-C and C-C-C, bond lengths 2.21 Å (Au-S), 1.81 Å (S-C), 1.541 Å (C-C), and a contribution of 1.92 Å from the methyl group.

    • Models with all the molecules swiveled 0° or 30° from the perpendicular to the rows could also fit most of the criteria fulfilled by the herringbone model proposed here, such as film thickness or optimized van der Waals molecular distance, but not other as head-to-head arrangement. The latter, moreover, has a larger empty distance between rows, and consequently, the measured corrugation would be approximately equal to the alkane chain diameter (4.3 Å), much larger than the corrugation measured here (1.44 Å).
