Smectic-A-Like Ordering Induced by the Free-Surface of 4,N-Ocyloxybenzoic Acid Liquid-Crystal Droplets
We report on onset of a surface induced phase in droplets of OO BA liquid crystals desplaying optical properties typical for the smectic-il state. The latter state does not exist in the bulk phase diagram of the system. The surface phase appears in a temperature range close to the bulk nematic- smectic-C transition temperature T-NC. The results are interpreted through a Landau-de Gennes type model with additional S-function terms.
