| 1 | Field-induced phase transitions in chiral smectic liquid crystals studied by the constant current method显示文摘In ferroelectric liquid crystals, phase transitions can be induced by an electric field. The current constant method allows these transition to be quickly localized and thus the(E, T) phase diagram of the studied product can be obtained.In this work, we make a slight modification to the measurement principles based on this method. This modification allows the characteristic parameters of ferroelectric liquid crystal to be quantitatively measured. The use of a current square signal highlights a phenomenon of ferroelectric hysteresis with remnant polarization at null field, which points out an effect of memory in this compound. | H Dhaouadi R Zgueb O Riahi F Trabelsi T Othman | 2016 | Chinese Physics B2016，25，5： | 0 |
