Abstract(in Japanese) (See Japanese page)
Abstract(in English) The dielectric properties of liquid crystal materials containing an ionic substance are analyzed in terms of space charge polarization. The theoretical equations for the dielectric constant and the dielectric loss factor derived by eliminating a condition that the diffusion distance in a period of the external AC field is much smaller than the thickness of specimen can successfully explain the experimental results for the liquid crystal material 5CB. It is found that the value of diffusion coefficient obtained by the theoretical analysis is significantly close to the value obtained by Time-of-Flight method.
