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…
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…
Freedericskz Transitions in the Nematic and Smectic ZA Phases of DIO
J. T. Gleeson, S. N. Sprunt, A. Jákli +2
The remarkable material DIO presents fascinating behaviors. It has been extensively studied as one of the first materials exhibiting a ferroelectric nematic phase. However, at high…
Giant Electro-Viscous Effects in Polar Fluids with Paraelectric-Modulated Antiferroelectric-Ferroelectric Phase Sequence
Hiroya Nishikawa, Péter Salamon, Marcell Tibor Máthé +2
The recently discovered ferroelectric nematic liquid-crystal material DIO exhibits an antiferroelectric (AF) phase, characterized by a sinusoidally modulated structure between the…
Transient Negative Capacitance in Ferroelectric Nematic Liquid Crystals
Netra Prasad Dhakal, Alex Adaka, Robert J. Twieg +1
The transient negative capacitance (NC) of solid ferroelectric materials used in field effect transistors can reduce the power dissipation of electronics. Here we show that similar…
