Optical Switching Properties of an Azo-Containing Banana-Shaped Liquid Crystal
By triangular wave method, the switching currents of an azo-containing banana-shaped antiferroelectric liquid crystal were investigated as a function of temperature. As the temperature increases from 150 to 175oC, the switching currents of the banana-shaped liquid crystal were observed to decrease linearly with the temperature. The unusual temperature-dependent polarization was discussed in the light of Landau-de Gennes theory.
