Abstract
Electrically induced azimuthal rotation of periodic structure of linear defects formed within cholesteric layer under planar-conical boundary conditions during relaxation from homeotropic state has been studied. It has been shown that when applying a voltage in the range 0 ≤ U ≤ 1,8 V, the periodic structures oriented at different azimuthal angles (within 90°) depending on the field values can be formed.
