| Description | Journal: Japanese Journal of Applied Physics 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. |
