Polar and apolar light-induced alignment of ferroelectric nematic at photosensitive polymer substrate
Ruslan Kravchuk, Oleksandr Kurochkin, Vassili G. Nazarenko +4
Surface alignment of a recently discovered ferroelectric nematic liquid crystal (NF) is usually achieved by buffed polymer films, which produce a unidirectional polar alignment of…
Helix alignment, chevrons, and edge dislocations in twist-bend ferroelectric nematics
Bijaya Basnet, Priyanka Kumari, Sathyanarayana Paladugu +6
We explore surface alignment and edge dislocations in the recently discovered twist-bend ferroelectric nematic, NTBF, in which the vector of spontaneous polarization follows an obl…
Director-layer dynamics in the antiferroelectric smectic-ZA phase of a ferroelectric nematic liquid crystal
Arjun Ghimire, Bijaya Basnet, Hao Wang +7
A dynamic light scattering study of director-layer fluctuations in the antiferroelectric smectic-ZA phase of the ferroelectric nematic liquid crystal DIO is reported. The dynamics…
Periodic splay Fréedericksz transitions in a ferroelectric nematic
Bijaya Basnet, Sathyanarayana Paladugu, Oleksandr Kurochkin +5
Electric field-induced splay of molecular orientation, called the Fréedericksz transition, is a fundamental electro-optic phenomenon in nonpolar nematic liquid crystals. In a ferr…
