Abstract

Dielectric relaxation and calorimetric investigations were performed on different smectic phases. Discontinuities of the critical frequency were found at both S//A-S//B and S//B-S//E phase transitions. S//A and S//E structures can be regarded as two-dimensional liquid and two-dimensional crystal, respectively. The low frequency dielectric dispersion presented here demonstrates the difference between the S//E and a three-dimensional crystal where this phenomenon is absent.
