    • Rutherford backscattering measurements show that the Shiraki oxidation produces an 8 to 9 Å thick oxide layer assuming the formation of stochiometric [formula omitted] Since the average oxygen concentration is believed to be lower than the perfect stochiometry, this thickness is a lower limit.

    • As described in Ref. 13 (pp. 228–232), electronic screening is relevant in the intensity calculation of modes polarized perpendicular to the optical plane (along the z axis). The determination of [formula omitted] is, however, difficult. For H on Si (100), it has been experimentally estimated to be 1.4 [ see edited by G. LeLay, J. Derrien, and N. Boccara, Springer Proc. Phys., Vol. 22, (Springer, Berlin)

    • for H on Si (111) it has been theoretically estimated to be 1.2 [see We find here that a value of 2.0 is necessary to account of the A mode on both flat and stepped surfaces. Although this is a slightly more accurate experimental determination of [formula omitted] than that for H on Si(100), the error bars are still large: 20% (i.e., [formula omitted]), due to the large distribution of the terrace lengths and the uncertainty in cutting and polishing. We note that, if the Si-H bond is, in fact, inclined with respect to the 〈111〉 axis on stepped surfaces due to interaction with steps, then a value lower than 2.0 would be needed to account for the data.
