Dielectric response of a ferroelectric nematic liquid crystalline phase in thin cells
Nataša Vaupotič, Damian Pociecha, Paulina Rybak +4
We studied dielectric properties of a polar nematic phase (NF) sandwiched between two gold or ITO electrodes, serving as a cell surfaces. In bulk, NF is expected to exhibit a Golds…
Multiple polar and non-polar nematic phases
S. Brown, E. Cruickshank, J. M. D. Storey +5
Liquid crystal materials exhibiting up to three nematic phases are reported. Dielectric response measurements show that while the lower temperature nematic phase has ferroelectric…
Multi-level Chirality in Liquid Crystals Formed by Achiral Molecules
Mirosław Salamończyk, Nataša Vaupotič, Damian Pociecha +6
In many biological materials with a hierarchical structure there is an intriguing and unique mechanism responsible for the 'propagation' of order from the molecular to the nano- or…
Nature of nematic to twist bend nematic phase transition
Damian Pociecha, Catriona Crawford, Daniel A. Paterson +4
The critical behavior at the transition from uniform nematic to twist-bend modulated nematic phase is revealed and shown to be well explained by the mean field approximation. The s…
Polarization gratings spontaneously formed by the helical Twist-Bend Nematic phase
N. Vaupotič, M. Ali, P. W. Majewski +2
Spontaneous formation of polarization gratings by liquid crystals made of bent dimeric molecules is reported. The grating is formed within the temperature range of the twist bend m…
Structural studies of the bond-orientational order and hexatic-smectic transition in liquid crystals of various compositions
I. A. Zaluzhnyy, R. P. Kurta, E. A. Sulyanova +9
We report on X-ray studies of freely suspended hexatic films of three different liquid crystal compounds. By applying angular X-ray cross-correlation analysis (XCCA) to the measure…
