Postradiation effects during a phase transition in liquid crystals - Emission of electrons and electromagnetic pulses
Abstract
The effect of irradiation on the characteristics of electron emission (EE) from liquid crystals undergoing a phase transition was investigated by measuring temperature dependences of the EE intensity (EEI) and transmission coefficient in crystals of cholesteryl caprinate (CC) undergoing the liquid crystal-solid crystal phase transition, for crystals exposed to X-rays and for nonirradiated crystals. The temperature dependence plots of the EEI and transmission coefficient indicate that the mechanism of the EE effects in the solidifying medium involves the transformation of the hypomolecular structure of the CC mesogen and the electrokinetic phenomena in the phase transition and in noncoherence regions.
