Soft modes of the dielectric response in the twist-bend nematic phase and identification of the transition to nematic splay bend phase in the dimer CBC7CB
K. Merkel, A. Kocot, C. Welch +1
The dielectric spectra of the twist bend nematic phase of the bent shaped achiral liquid crystal dimer are studied for the determination of the different relaxation modes. The two…

Tuning selective reflection of light by surface anchoring in cholesteric cells with oblique helicoidal structures
Olena S. Iadlovska, Graham R. Maxwell, Greta Babakhanova +4
Selective reflection of light by oblique helicoidal cholesteric (ChOH) can be tuned in a very broad spectral range by an applied electric field. In this work, we demonstrate that t…
