Electrooptic and Dielectric Studies in Cadmium Sulphide NanorodsFerroelectric Liquid Crystal Mixtures

الملخص EN

We present the results based on the electrooptic and dielectric studies in cadmium sulphide (CdS) nanorods/ferroelectric liquid crystal mixtures.

Doping of CdS nanorods increases the spontaneous polarization and response time, which due to large dipole-dipole interaction and increase in anchoring energies exists between nanorods and FLC molecules.

Dielectric measurements revealed a decrease (~40% for 0.3% CdS in FLC) in permittivity and dielectric strength in doped sample cell than pure FLC mixture.

A decrease in dc conductivity and relaxation frequency with doping concentration was also noticed.

The preexponent factor and fractional exponent factor are found as predicated by existing theories.
