Dielectric Study on the Alignment or Orientation of N(4-n-heptyloxy benzylidene)4'-n-butylaniline and the Anomalous Dielectric Behavior in the Smectic G Phase
The present article reports on the alignment or orientation of a particular compound N(4-n-heptyloxy benzylidene)4 '-n-butylaniline through dielectric study. The effect of using two different alignment layers (for homogenous alignment) and doping silver nanoparticles (0.25% by weight) on the behavior in dielectric property with varying temperature and biasing electric field was studied in terms of liquid crystal alignment or orientation using the mechanism proposed by earlier workers. The study includes the anomalous dielectric behavior in SmG phase by presenting a technique for the analysis of the absorption process, which exists only in SmG phase at fixed frequency while varying temperature, is also presented.
