Paper Abstract

The dielectric response of thin surface stabilized ferroelectric liquid crystal cells with different aligning materials and filled with the same FLC mixture are studied and compared in the low frequency dielectric regime. For the measurements we adopted an improved cell structure with metallized pixel connections. In the FLC material in question, Merck SCE 13, only one absorption appears corresponding to a collective mode.It is ascribed to the Goldstone mode in the bulk FLC. From our measurements we calculate the surface anchoring energy density for the different aligning materials and discuss changes induced in dielectric spectra by a DC bias field.
