Figure 1

Reflectivity curves derived from the proposed dry SAM fit in the Comment [3]. The parameters are those used in the Comment, except (a) SAM layer removed; (b) ${\mathrm{SiO}}_2$ layer removed; (c) all layers present, but $\mathrm{Si}-{\mathrm{SiO}}_2$ interface width increased from 0.5 to 2 Å—this curve is shifted downwards for clarity. The data points (shown twice) are from our Letter.Reuse & Permissions
