Crystal Mixture

Electric-field effects were investigated in a planar-aligned nematic liquid crystal mixture. Under a DC electric field, we observed the presence of domains. The domain structure changed near the threshold field. The effects of charge injection from the substrate surfaces were investigated. The work function is calculated using Richardson's equation.PACS No.: 61.30.Hn

Director Orientation

A two-dimensional model of Fredericks effect was used for the investigation of the static electric field influence on nematic liquid crystal director orientation in the side-electrode cell. The solutions of the equations describing the model were obtained by finite-difference methods. Fredericks transition threshold for the central part of the cell, as well as dependencies of the distribution of the director orientation patterns on the electric field and location, were obtained. The numerical results are found to agree qualitatively with the experiment. Further investigations are needed to elucidate completely the Fredericks effect.
