TWAXS-derived surface coverage by ordered domains of C14F monolayers, as a function of local surface height h. (a) Calculated TWAXS intensity correction factors, for X-ray absorption through bulk meniscus water (dotted line; for 13.5 keV X-rays used), surface tilt (dashed line) and the product of the two (solid line). (b) Normalized surface coverage extracted from the background-subtracted, meniscus-corrected peak TWAXS intensities observed at the horizon ([\varphi] = [\pi/2]), before (circles) and after (squares) LB deposition. The coverage for h < hmax corresponds to Langmuir monolayers at the air–meniscus water interface; the coverage for h > hmax is for LB monolayers transferred onto the Si substrate.
