Surface-induced multiple re-entrant transitions
PANOV, VITALY; VIJ, JAGDISH KUMAR (2006)We have studied tilted surface layers in the bulk SmA temperature window of one liquid crystal using null transmission ellipsometry. Five distinct nonplanar surface structures were observed. We present analyses of the tilt ... -
Temperature-induced sign reversal of biaxiality observed by conoscopy in some ferroelectric Sm- C* liquid crystals
FUKUDA, ATSUO; VIJ, JAGDISH KUMAR (2007)We have studied various ferroelectric liquid crystals to find the average molecular direction of the shortest axis in the perfectly unwound state by using tilted conoscopic measurements. We find that there exist two types ... -
Two kinds of the smectic-C subphases in a liquid crystal and their relative stability dependent on the enantiomeric excess as elucidated by the electric field induced birefringence experiment
VIJ, JAGDISH KUMAR; FUKUDA, ATSUO (The American Physical Society, 2005)The electric-field-induced birefringence has been investigated by using a photoelastic modulator, with a view to obtaining a molecular model for the subphases produced by the frustration between ferroelectricity and ...
