Abstract:

First, the grain size effect on ferroelectricity, phase transformation, lattice dynamics, and photoluminescence properties of nanocrystalline BaTiO3 were studied. Second, the orientation mechanism, optical and electrical properties of highly oriented lead zirconate titanate thin film heterostructures prepared by chemical solution methods were studied. Third, the factors determining the performance of monolithic ferroelectric thin film infrared focal plane arrays were investigated using a modeling method.

Key words: nanocrystalline BaTiO3, grain size effect, phase transformation, oriented ferroelectric thin film heterostructures, distributed parameter model of ferroelectric film infrared microsensor
