Abstract:
Surface anchoring of molecules liquid crystals molecules influence local orientational order properties in nematic cells. Two of the most common types of anchoring are parallel (planar anchoring) and perpendicular (homeotropic anchoring). Using computer simulations, we investigate influence of the temperature and of electric field on the tensor order parameter for both types of anchoring. We concluded that, in both the presence or the absence of the electric field, temperature play a central role in determining the orientation of the liquid crystal molecules.
