Abstract

Quasi-static orientation transitions in nematic-cholesteric liquid crystal (LC) droplets occurring in an isotropic environment in a constant electric field have been studied as dependent on the concentration of a chiral (cholesteric) dopant. In the case where the droplet radius is smaller than (or on the order of) the helix pitch induced by the chiral dopant (RP), there exists a critical concentration of the dopant above which the interface with the isotropic phase initiates an increase in the deformation field with a correlation length dependent on the decreasing P value.
