Giant Electroclinic Effect in Chiral Smectic A Phase of Ferroelectric Liquid Crystals
スポンサーリンク
概要
- 論文の詳細を見る
A giant electroclinic effect was observed in smectic A (S_A) phases of various ferroelectric liquid crystals with spontaneous polarizations as large as several hundred μC/m^2. An induced tilt angle increased linearly with an electric field, E, and tended to saturate toward 16°. The induced tilt angle of a few degrees was observable even at a temperature 20° above the S_A-S^*_C transition. It was confirmed using several compounds that the induced tilt angle is proportional to the spontaneous polarization in S^*_C. The response time is less than 1 μs and, when normalized by the induced tilt angle, linearly depends on E, i.e., τ'/θ_0∝E.
