Abstract

This paper discusses the features of the switching dynamics of the phase lag of light by 2π and 4π in cells with a dual-frequency nematic liquid crystal as a result of bend and splay deformation of layers with oblique homeotropic orientation by means of an electric field with frequency 30kHz and as a result of relaxation when a low-frequency field of 1kHz is applied. The slope angle of the director was varied from 36° to 84° by means of cerium oxide layers obliquely deposited in vacuum. Studies of the surface texture of the orienting layers by means of atomic-force microscopy showed that this is achieved as a result of variation of the surface nanotexture.
