Anomalous temperature dependence of layer spacing of de Vries liquid crystals: Compensation model
VIJ, JAGDISH (2016)Smectic liquid crystals that exhibit temperature independent layer thickness offer technological advantages for their use in displays and photonic devices. The dependence of the layer spacing in SmA and SmC phases of de ... -
Biaxial order and a rotation of the minor director in the nematic phase of an organo-siloxane tetrapode by the electric field
VIJ, JAGDISH (2012)Biaxiality in the nematic phase for a liquid crystalline tetrapode made up of organo-siloxanes mesogens is investigated using polarized infrared spectroscopy. An ordering of the minor director for the homeotropically aligned ... -
Conoscopy of chiral smectic liquid crystal cells
VIJ, JAGDISH; SONG, JANG-KUN (2008)The conoscopic method for investigating the optical properties of a liquid crystal cell is studied with the aim of determining the effects of the approximations used in the calculation on the results. We confirm that the ... -
Debye process and dielectric state of an alcohol in a nonpolar solvent.
VIJ, JAGDISH (2011)To investigate the origin of the first order molecular kinetics of the most prominent, Debye-type polarization, a detailed dielectric relaxation study of 66.5, 40, and 20 mole solutions of 5-methyl-2-hexanol in 2-methylpentane ... -
Dielectric and electro-optic studies of a bimesogenic liquid crystal composed of bent-core and calamitic units
VIJ, JAGDISH; PANOV, VITALI (2014)A bimesogen, BR1, composed of a bent-core and calamitic unit, linked laterally via a flexible spacer is investigated by dielectric and electro-optic techniques. X-ray results show the presence of clusters in the nematic ... -
Effect of cybotactic clusters on the elastic and flexoelectric properties of bent-core liquid crystals belonging to the same homologous series
VIJ, JAGDISH; PANOV, VITALI (2013)We report results of the splay ( K 11 ) and bend ( K 33 ) elastic constants and the effective flexoelectric coefficient of three bent-core liquid crystals belonging to a homologous series of 4-cyanoresorcinol ... -
Effect of molecular-scale surface morphology on the surface melting of liquid crysals on self-assembly monolayers
VIJ, JAGDISH (2014)We devised liquid crystal cell substrates with different surface roughnesses at the molecular scale by controlling the density of two types of trichlorosilanes with different alkyl chain lengths. We investigated surface ...
