Outline of Final Research Achievements

Ion-doped nematic liquid crystals (NLCs) can exhibit rich electro-hydrodynamic phenomena when an ac electrical voltage is applied. In this work, we use the electro-hydrodynamic effects to to control the colloidal aggregation. By using various NLCs and alignment layers, we have found that colloidal particles form some characteristic structures. Moreover, for a specific experimental condition, we have observed a pattern formation of an NLC which is caused by the ionic contribution.
