Polarization patterning in ferroelectric nematic liquids via flexoelectric coupling

open access: yesNature Communications, 2023
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.

Distortional Lifshitz Vectors and Helicity in Nematic Free Energy Density [PDF]

open access: yes, 2013
Here we discuss the free energy of nematic liquid crystals using two vectors and the helicity, with the aim of having a compact form of its density. The two vectors are due to the splay and bend distortions of the director field. They have a polar nature,

Optical Response Associated with the Orientation and Structure of Liquid Crystals with Respect to Phosphatidylcholine Concentration

open access: yesCrystals, 2021
Based on the anchoring effect due to the self-assembling behavior of the phospholipid molecules at the interface between the liquid crystal and water phases on the orientation of liquid crystals, the optical response associated with the orientation and ...

Eliminating Ambiguities in Electrical Measurements of Advanced Liquid Crystal Materials

open access: yesCrystals, 2023
Existing and future display and non-display applications of thermotropic liquid crystals rely on the development of new mesogenic materials. Electrical measurements of such materials determine their suitability for a specific application.

Nematic liquid crystal alignment on subwavelength metal gratings

open access: yesBeilstein Journal of Nanotechnology, 2018
We have studied the alignment of a nematic liquid crystal (LC) material on aluminum subwavelength nanogratings as a function of the period, p, and the slit width to period ratio, w/p.
