Abstract

We studied 4-p-decyloxybenzoic acid 4′-p-hexyloxyphenyl ester liquid crystals of the smectic C (smC) type in which a wavelike instability is induced by an external electric field in the vicinity of the smC-smA phase transition. The smectic layers in a liquid-crystal sample placed in a sandwich type cell were parallel to the cell plates and the director was oriented at an angle θ to the layer normal. The second-order smC-smA phase transition exhibits a critical character. A wavelike instability in the form of a band structure was observed in both alternating and constant electric fields. The band structure period depends on the electric field strength.
