dc.description.abstractFe3O4 nanoparticles were doped into E63 coded liquid crystal (LC) with 0.1 wt% to investigate the effect of Fe3O4 on the electrical and dielectric properties of LC in a wide range of frequency, bias voltage, and illumination. The frequency, bias voltage, and illumination level dependence of the electrical and dielectric properties of pure E63 and doped mixture (E63-Fe3O4) has been investigated using the current-voltage (I-V) and admittance spectroscopy (C-V and G/omega-V) data in the frequency range of 10 kHz - 1 MHz at room temperature. Results show that the increment in current with Fe3O4 doping is due to the metallic nature of the Fe3O4 nanoparticles. The current switching voltage of reorientation is shifted to lower voltage values as a result of Fe3O4 doping. Same behavior is also observed with increasing illumination level. The polarization contribution of Fe3O4 doping is evident considering the values of Delta epsilon' = epsilon'(E63/Fe3O4) - epsilon'(E63) at low frequencies. Moreover, depending on the existence of Fe3O4 doping agent, there is a split in sigma(ac)-f plots where sigma(ac) values increase with frequency, especially at high frequencies.en_US
