Micro-second response time in near isotropic phase liquid crystal at room-temperature
Résumé
Near isotropic phase is a highly symmetric nematic phase (order parameter: Q is very close to zero) usually exists over a small temperature range near to the N-I phase transition temperature of any liquid crystal material, be- cause of that it is often called as superheated nematic phase. Realization of this phase normally required high temperature, except for the typical material whose N-I phase transition temperature is near to the room temper- ature. The prime objectives of this article are to show that the superheated nematic phase can even exist at room temperature for any liquid crystal and hence to propose a platform towards high orientational speed electro- optic applications as well as non-linear optical processes in this phase at room temperature.
