摘要

The dynamic manipulation of the helicity in a cholesteric helical superstructure could enable precise control over its physical and chemical properties,thus opening numerous possibilities for exploring multifunctional devices.When cholesteric material satisfies the sufficiently small bending elastic effect,an electrically induced deformation named the cholesteric heliconical superstructure is formed.Through theoretical and numerical analysis,we systematically studied the tunable helicity of the heliconical superstructure,including the evolution of the corresponding oblique angle and pitch length.To further confirm the optical properties,Berreman's 4 × 4 matrix method was employed to numerically analyze the corresponding structure reflection under the dual stimuli of chirality and electric field.
