Nonlinear electrophoretic motion of dielectric microparticles in nematic liquid crystals

摘要

The motion of dielectric microparticles induced by external ac electric Held, E, was investigated in the cell with in-plane stripe electrodes and filled with homeotropically aligned nematic liquid crystal. It was demonstrated that the average velocity of the microparticles depended on the third power of the electric field strength (v = μ~((3))E~3). The experimental results were explained by the induced charge electrophoresis.
