Calorimetric and optical investigation of the nematic, splay-nematic, and ferroelectric nematic phases of RM734 liquid crystal
Marta Lavrič, Nerea Sebastián Ugarteche, Calum Jordan Gibb, Richard J. Mandle, Alenka Mertelj, Nikola Novak, George Cordoyiannis
Izvirni znanstveni članek
Oznake: tekoči kristali;ferroelektrika;
RM734 is one of the first two liquid crystal compounds reported to exhibit the ferroelectric nematic phase. At the early stage of its characterisation, a direct nematic – to – ferroelectric nematic phase transition was reported for this compound. However, subsequent studies revealed the presence of ...

The investigation of phase behaviour in the new class of materials showing ferroelectric nematic and related phases can greatly benefit from methods that combine thermal control with structural and polarity-sensitive imaging. In this work, we present a technique that integrates focused infrared lase ...

Antiferroelectric order in nematic liquids
Peter Medle Rupnik, Ema Hanžel, Matija Lovšin, Natan Osterman, Calum Jordan Gibb, Richard J. Mandle, Nerea Sebastián Ugarteche, Alenka Mertelj
Izvirni znanstveni članek
Oznake: feroelektrične nematske tekočine;ferroelectric nematic liquids;flexoelectricity;antiferroelectric order;
The recent discovery of ferroelectric nematic liquid crystalline phases marks a major breakthrough in soft matter research. An intermediate phase, often observed between the nonpolar and the ferroelectric nematic phase, shows a distinct antiferroelectric response to electric fields. However, its str ...

Ferroelectric nematic fluids are promising materials for tunable nonlinear photonics, with applications ranging from second harmonic generation to sources of entangled photons. However, the few reported values of second-order susceptibilities vary widely depending on the molecular architecture. Here ...
