Description
Summary:We report calorimetric, X ray, electrooptic, electric-field and dielectric experiments conducted on the recently discovered undulated twist grain boundary-C super(*) liquid crystal. The results are discussed on the basis of the structure of this new phase which is characterised by a two-dimensional modulation orthogonal to the TGB helical axis and a helical arrangement of the molecular director within the smectic blocks.
