During the last years, several groups across the world have concentrated on the adaptation and further development of electrospinning (e-spinning) to enable ceramic fiber synthesis. Thus far, more than 20 ceramic systems have been synthesized as micro-and nanofibers. These fibers can be amorphous, polycrystalline, dense, porous, or hollow. This article reviews the experimental and theoretical basis of ceramic e-spinning. Furthermore, it introduces an expanded electro hydrodynamic (EHD) theory that allows the prediction of fired fiber diameter for lanthanum cuprate fibers. It is hypothesized that this expanded EHD theory is applicable to most ceramic e-spinning systems. Furthermore, electroceramic nanofibers produced via espinning are presented in detail along with an overview of electrospun ceramic fibers. J ournal

Pb͑Zr, Ti͒O 3 ͑PZT͒ thin films with ͑100͒ preferred orientation were prepared using metalorganic chemical vapor deposition on LaNiO 3 ͑LNO͒ buffered platinized Si with thickness varying from 25-100 nm. The dependence of electrical properties of PZT films on thickness was studied using several techniques, including polarization-electric field (P-E), temperature variable currentvoltage (I-V), and capacitance-voltage (C-V) measurements. Because of the formation of Schottky barriers at ferroelectric/electrode interfaces, built-in electric fields are present. A progressive increment in carrier concentration and interfacial built-in electric field versus reducing PZT film thickness was observed, which is believed to be a dominant factor controlling the measured dielectric/ferroelectric properties. The higher built-in electric field in thinner PZT films would pin the dipoles at the interfacial region and retard the response of dipoles to the external electric field.

Dense, high-index, and reproducible scandium oxide (Sc2O3) thin films with high mechanical strength were grown on glass substrates by metalorganic chemical-vapor deposition. The influence of deposition temperature on the microstructure evolution and optical properties of Sc2O3 thin films was investigated by x-ray diffraction, scanning electron microscopy, atomic-force microscopy, transmission electron microscopy, and spectrophotometry. A close relationship between microstructure and optical properties was found for Sc2O3 thin films prepared at different deposition temperatures.
