Analyzing interfacial structures in liquid crystal cells, revealing links to material properties and assembly.
The structure of interfacial boundaries in a liquid crystal (LC) cell, composed of sequential layers of a thin-film electrode, an alignment polymer coating, and a ferroelectric LC, was investigated using X-ray scattering and atomic force microscopy. Quantitative parameters describing the structure of transition layers were obtained, along with statistical data on interface roughness and dielectric constant distribution across the film. These data are expected to provide a link between the roughness and anchoring properties of LC materials at interfaces and give an assessment of the structural modifications occurring at each stage of the electro-optical cell assembly.
