Abstract: | The dielectric constant and the dielectric loss of 5-n-pentyl-2-4-n-nonyloxyphenyl]-1,3-dioxane were investigated in the region of 0.1 to 10 MHz. An isotropy temperature was detected, at which the static dielectric anisotropy Δε01 = 0. Using both the Freedericksz and the DAP effect, we measured the frequency dependence of the threshold voltage U0 and compared the results with those of the dielectric measurements. In the case of DAP effect we could find two different types of dispersions curves of U0. |
