Ionizing radiation effect on the Frederics effect in nonmatic liquid crystals

Ionizing radiation effects on the electric conductivity of nonmatic liquid crystals (NLC), space charge formation and the Frederics effect are studied. The carried-out calculations shown that ionizing radiation effect much depends on NLC properties. For NLC with high A parameter values and low δ parameter values the Frederics transition voltage remains constant, while at A ≅ 1 and δ > 0.6 the relative voltage variation attains 12 %. Radiation intensities in this case does not cause essential sample heating. 1 ref.; 3 figs
