A rotation mechanism of nematic cholesteric droplets in a DC electric field

Dynamics of orientation transformations in nematic cholesteric droplets in isotropic environment under action of dc electric field is studied experimentally. The droplets are considered with an equilibrium pitch of the helix smaller than radius of a droplet. It has been shown that, the dynamics of the rotation motion of the droplets in the dc electric field is determined by a flexoelectic mechanism.
