Shear-mode Direct Piezoelectric Response of Ferroelectric Nematic Liquid Crystals
Péter Salamon, Marcell Tibor Máthé, Hiroya Nishikawa +2
Piezoelectricity (linear coupling between mechanical deformation and electric signal) was originally observed only in solid crystals. Recently, it was discovered that liquid ferroe…
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…
Ferroelectric nematic liquid crystal thermo-motor
Marcell Tibor Máthé, Ágnes Buka, Antal Jákli +1
A thermal gradient-induced circular motion of particles placed on ferroelectric nematic liquid crystal sessile drops is demonstrated and explained. Unlike hurricanes and tornadoes…
