Description 695-699
Employing the thermodynamic model which is centred on Landau-de-Gennes theory, the electro-optical properties of the
Sm𝐶􀮺
∗ phase in antiferroelectric mesogen has been studied. The wave vector q, the polarisation vector P, and the couplings
between these order parameters are used to express the system's free-energy density. The Landau coefficients involved in the
free-energy density have been computed using experimental data of tilt angle and spontaneous polarisation in the Sm𝐶􀮺
∗
phase of chiral compounds (6F2OBi and 3F5HBM6(S)). Theoretical and experimental data have been compared in
investigations
