| Abstract: | Effect of dc electric field on a homeotropically oriented liquid crystal mixture of positive dielectric anisotropy, has been studied. Detailed studies on electrohydrodynamic (EHD) instability were carried out on liquid crystal cells of four different thicknesses. Microscopic studies of its textures at different voltage were also carried out. Existence of charge injection, charge diffusion and convective flow of liquid in the liquid crystal cells was observed. Effects of anisotropy in viscosity, dielectric permittivity and other physical parameters on electric current through the sample cells were discussed. |
