Abstract : The structure and switching dynamics of ferroelectric solid state and liquid crystal thin films were investigated experimentally using x-ray scattering, dielectric measurements, and optical microspectroscopy. Crystalline piezoelectric ferroeletric films, formed by sol-gel and sputter deposition, were developed and analyzed for application as high speed nonvolatile memories. Ferroelectric liquid crystal devices were studied for application as fast electro-optic light valves in spatial light modulator applications. A novel thermo optical effect in ferroelectric lead magnesium niobate suitable for use in pressure sensing applications was discovered....
