  • Title: Flexoelectricity in chiral nematic liquid crystals as a driving mechanism for the twist-bend and splay-bend modulated phases.
    Author: Vaupotič N, Čepič M, Osipov MA, Gorecka E.
    Journal: Phys Rev E Stat Nonlin Soft Matter Phys; 2014 Mar; 89(3):030501. PubMed ID: 24730777.
    Abstract:
    We present a continuum theoretical model describing the impact of chirality on nematic systems with large flexoelectricity. As opposed to achiral materials, where only one type of the modulated structure can exist in a given material, the model predicts that chirality can stabilize several modulated phases, which have already been observed experimentally [A. Zep et al., J. Mater. Chem. C 1, 46 (2013)].
