) phase transition. Such reduction in the splay elastic constant, which is a deviation from conventional nematic behaviour, is attributed to flexoelectric coupling becoming significant at these temperatures. Corrections with temperature dependent flexoelectric coupling for the elastic constants, dielectric permittivity, and Fréedericksz threshold voltage, are discussed in detail.
