Fredericksz transition threshold in nematic liquid crystals filled with ferroelectric nano-particles
A key liquid crystalline property for electro-optic applications is the Fredericksz threshold electric field. There has been recent experimental interest in liquid crystal-based colloidal suspensions in which the colloidal nanoparticles both possess a permanent electric polarization and provide strong director anchoring on the particle surface. Such suspensions are sometimes known as Filled Liquid Crystals. Our calculations suggest, in qualitative agreement with experiment, that filling the nematic liquid crystal with ferroelectric nanoparticles can significantly decrease the electric Fredericksz transition threshold field.
