Landau theory applied to antiferroelectric ordering in ferroelectric nematic liquid crystals
Manisha Badu, Arjun Ghimire, Milon +6
The polarization and density modulation associated with antiferroelectric ordering is studied experimentally as a function of temperature in two ferroelectric nematic liquid crysta…
Electrochromic chiral ferroelectric nematic liquid crystals
Md Sakhawat Hossain Himel, James T. Gleeson, Robert J. Twieg +2
Chiral nematic liquid crystals are one-dimensional photonic band-gap materials whose reflection wavelength can be well tuned by temperature, but only limited and irreversible tunin…
Low-Power Temperature Control by Chiral Ferroelectric Nematic Liquid Crystal Windows
Md Sakhawat Hossain Himel, Rohan Dharmarathna, Netra Prasad Dhakal +5
Low power consumption is critical for smart windows for temperature control and privacy. The recently discovered ferroelectric nematic liquid crystals exhibit strong coupling of th…
Ferroelectric Nematic and Smectic Liquid Crystals with Sub-Molecular Spatial Correlations
Parikshit Guragain, Arjun Ghimire, Manisha Badu +6
A number of highly polar three ring rod-shaped compounds with a terminal thiophene ring have been synthesized and the physical properties of a subset are reported in detail. On coo…
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…
