Electrooptics of mm-scale polar domains in the ferroelectric nematic phase
Nerea Sebastián Ugarteche, Richard J. Mandle, Andrej Petelin, Alexey Eremin, Alenka Mertelj
Izvirni znanstveni članek
Oznake: polar nematic;ferroelectric splay nematic;surface effects;electro-optic behaviour;second harmonic generation;
The recent discovery of the ferroelectric nematic phase has opened the door to experimental investigation of one of the most searched liquid crystal phases in decades, with high expectations for future applications. However, at this moment, there are more questions than answers. In this work, we exa ...

Polarization patterning in ferroelectric nematic liquids via flexoelectric coupling
Nerea Sebastián Ugarteche, Matija Lovšin, Natan Osterman, Andrej Petelin, Irena Drevenšek Olenik, Alenka Mertelj
Izvirni znanstveni članek
Oznake: liquid crystals;nonlinear optics;
The recently discovered ferroelectric nematic liquids incorporate to the functional combination of fluidity, processability and anisotropic optical properties of nematic liquids, an astonishing range of physical properties derived from the phase polarity. Among them, the remarkably large values of s ...

We report on observations of optical switching in bent-core liquid crystals possessing azocinnamoyl groups in both elongated side arms. UV-activated switching was observed in two of the synthesised materials, both of which were studied optically and with dielectric spectroscopy. Polarising microscop ...

Running streams of a ferroelectric nematic liquid crystal on a lithium niobate surface
Luka Cmok, Virginie Coda, Nerea Sebastián Ugarteche, Alenka Mertelj, Marko Zgonik, Satoshi Aya, Mingjun Huang, Germano Montemezzani, Irena Drevenšek Olenik

Oznake: fizika kondenzirane snovi;feroelektrični nematski tekoči kristali;električno polje;condensed matter physics;ferroelectric nematic liquid crystals;electric field;
Sessile droplets of a ferroelectric nematic liquid crystalline material were exposed to surface electric fields produced by pyroelectric and photogalvanic (photovoltaic) effects in X-cut iron-doped lithium niobate crystals. The resulting dynamic processes were monitored by polarisation optical (vide ...
