Abstract

Chemisorbed monolayers of decyltrichlorosilane, [11-(2-Naphthyl)undecyl]trichlorosilane, and a coadsorbed binary mixture of the two were prepared and subsequently investigated using lowangle x-ray reflectivity. Electron density profiles calculated from this data combined reveal well-defined naphthyl and alkyl regions in the [11-(2-Naphthyl)undecyl]trichlorosilane monolayer indicating a high degree of registry along the film normal. These conclusions are consistent with previous spectroscopic measurements of the same system.
