DC電場下におけるネマチック液晶のソフトモード

抄録

The dielectric dispersion of the nematic liquid crystal near the critical end point was measured under DC electric field. The permittivity increased near the phase transition temperature. To explain this result, the permittivity was calculated using Landau-de Gennes theory. It was clarified that the contribution of the soft mode becomes dominant near the critical point. In addition, the calculation results showed good agreement with the experimental results.
