1. Introduction
Liquid crystals (LCs) are among the most appealing condensed states of matter and their properties help understand us other condensed phases that exist in nature [1]. LCs have been the subject of intensive investigation due to their attractive aspects for both scientific studies and practical applications. Since LCs exhibit considerable optical anisotropy and can be tuned by applied fields or temperature variation, they are attractive candidates for electro-optical applications. LCs are also widely used in display systems because of the speed of their electro-optical switching and their low molecular weight.
It is well known that the ...
