Query: Electrooptics of mm-scale polar domains in the ferroelectric splay
  nematic phase   The recent discovery of the ferroelectric splay 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 examine
the formation and structure of large polar nematic domains of the ferroelectric
splay nematic material RM734 in planar liquid crystals cells with different
aligning agents and specifications. We observe that confining surfaces have a
strong influence over the formation of different types of domains, resulting in
various twisted structures of the nematic director. For those cells
predominantly showing mm-scale domains, we investigate the optical and second
harmonic generation switching behaviour under applications of electric fields
with a special focus on in-plane fields perpendicular to the confinement media
rubbing direction. In order to characterize the underlying structure, the polar
optical switching behaviour is reproduced using a simplified model together
with Berreman calculations.
