Alignment of liquid crystals on obliquely evaporated silicon oxide films

View publication

Abstract

Liquid crystal alignment on thin films obliquely deposited by electron beam evaporation of SiO2 is reported. Films deposited at a glancing angle of 5°give high tilt alignment ?45°, while increasing the deposition angle to 30°gives zero tilt alignment. Scanning electron microscope (SEM) pictures relate surface topography to alignment. The material and temperature dependence of tilt are reported. The tilt is constant through the nematic-smectic A transition.
