Ferroelectric and Hyper Dielectric modes in Ferronematic Liquid Crystals
Rahul Uttam, Neelam Yadav, Alexander Belik +4
Binary mixtures of the ferronematic compound DIO with recently reported non-ferroelectric material WJ-16 which shows Colossal Permittivity (CP) ~5000 and superparaelectricity (SPE)…
Some Peculiarities of Dielectric Spectroscopy in Ferroelectric Nematics
Yuri P. Panarin, Neelam Yadav, Rahul Uttam +3
Dielectric spectroscopy is known as one of the most powerful techniques for studying ferroelectric and other polar materials. Since the discovery of ferroelectricity in Liquid Crys…
Colossal Dielectric Permittivity and Superparaelectricity in phenyl pyrimidine based liquid crystals
Yuri P. Panarin, Wanhe Jiang, Neelam Yadav +6
A set of polar rod-shaped liquid crystalline molecules with large dipole moments (mu > 10.4-14.8 D), their molecular structures based on the ferroelectric nematic prototype DIO, ar…
Quantifying the contribution of material and junction resistances in nano-networks
Cian Gabbett, Adam G. Kelly, Emmet Coleman +18
Networks of nanowires and nanosheets are important for many applications in printed electronics. However, the network conductivity and mobility are usually limited by the inter-par…
Polar nature of the ferro-electric nematic studied by dielectric spectroscopy
Neelam Yadav, Yuri P. Panarin, Jagdish K. Vij +2
The nematic-nematic transitions in a nematic compound DIO are studied in homogeneously planar and homeotropic aligned cells using dielectric spectroscopy in the frequency range 0.1…
Detection of chiral domains and linear electro-optical response in planar-aligned cells of an achiral rod-like ferro-electric nematic liquid crystal

Chiral domains of opposite chirality are observed surprisingly in a nematic phase of an achiral rod-like liquid crystalline mesogen that shows ferroelectric nematic and antiferroel…
Electric field distortions in structures of the twist bend nematic (NTB) phase of a bent-core liquid crystal
K. Merkel, A. Kocot, J. K. Vij +1
Dielectric spectroscopy of a twist bend nematic phase of an achiral bent core liquid crystalline compound under DC bias is used to investigate its response to electric field. Two c…
Characterization of the sub-micrometer hierarchy levels in the twist-bend nematic phase with nanometric helices via photopolymerization. Explanation for the sign reversal in the polar response
Vitaly P. Panov, Sithara P. Sreenilayam, Yuri P. Panarin +3
Photo-polymerization of a reactive mesogen mixed with a mesogenic dimer, shown to exhibit the twist-bend nematic phase (), reveals the complex structure of the self-deforma…
Hierarchy of Periodic patterns in the twist-bend nematic phase of mesogenic dimers
Vitaly P. Panov, Michael C. M. Varney, Ivan I. Smalyukh +3
Several attractive properties of hydrocarbon-linked mesogenic dimers have been discovered, a major feature of these has been the ability of dimers under confinement to form periodi…
Nematic twist-bend phase with nanoscale modulation of molecular orientation
Volodymyr Borshch, Young-Ki Kim, Jie Xiang +8
A state of matter in which molecules show a long-range orientational order and no positional order is called a nematic liquid crystal. The best known and most widely used (for exam…
