Re. Geer et al., OFF-SPECULAR X-RAY-SCATTERING IN LANGMUIR-BLODGETT MULTILAYERS OF A LIQUID-CRYSTALLINE POLYMER, Physical review. E, Statistical physics, plasmas, fluids, and related interdisciplinary topics, 52(1), 1995, pp. 671-680
The effect of surface roughness on the static layer undulations of mul
tilayer films of a side-chain liquid-crystalline polymer has been inve
stigated by off-specular x-ray scattering. The roughness correlation l
ength evaluated from the off-specular data is shown to vary inversely
with the average roughness of the multilayer film. The features of the
off-specular x-ray scattering are similar to those exhibited by inorg
anic heterostructural films.
