PAb10 V字型スイッチングを示す液晶自己保持膜の楕円偏光解析

抄録

Ellipsometric studies have been conducted on freely-suspended films of an antiferroelectric liquid crystal mixture showing V-shaped switching. We observed discontinuous changes of the ellipsometric quantity Δ (phase difference between s- and p- components of transmitted light) at 46 ℃ indicating a phase transition from smectic-C^* to the ferrielectric phase, although, this transition is continuous in conoscopic figure results. Also, we discussed the details of Δ as a function of applied electric field in each phase.
