Dynamics of Smectic-C Point Disclinations in Freely-Suspended Liquid Crystal Films

Date The final copy of this thesis has been examined by the signatories, and we find that both the content and the form meet acceptable presentation standards of scholarly work in the above mentioned discipline. The motion of topological defects in the director field is observed in freely-suspended smectic-C liquid crystal films using reflected polarized light microscopy. We study the annihilat...

Surface energetics of freely suspended fluid molecular monolayer and multilayer smectic liquid crystal films.

A study of the surface energetics of the thinnest substrate-free liquid films, fluid molecular monolayer and multilayer smectic liquid crystal films suspended in air, is reported. In films having monolayer and multilayer domains, the monolayer areas contract, contrary to predictions from the van der Waals disjoining pressure of thin uniform slabs. This discrepancy is accounted for by modeling t...

Capacitive Interdigital Sensor with Inhomogeneous Nematic Liquid Crystal Film

The performance of capacitive interdigital sensors involved with anisotropic and inhomogeneous nematic liquid crystal (LC) film is investigated. These sensors have potential applications in chemical and biological systems. The theory for modeling the permittivity tensor of the LC film as a function of the molecular orientation is presented. The LC film is handled as inhomogeneous material where...
