Abstract:

A very important role is played by metal oxides in many areas of chemistry, physics, and materials science. Transition metal and rare-earth metal elements are able to form a large diversity of oxide compounds which can adopt an ample array of atomic structures and electronic properties that can exhibit metallic, semiconductor, or insulator characteristics. In technological applications, metal oxides are used in the fabrication of microelectronic components, sensors, fuel cells, coatings to protect surfaces against corrosion, and as catalysts. In this thesis we have decided to study two known c

In the work presented here, a synthetic and structural study of K2NiF4-related oxides and oxide fluorides is reported.

Many of these materials are novel, and show some interesting structural, chemical and physical properties. These materials were all prepared via the standard solid state technique. Because most of the oxide fluorides presented here are not stable at high temperatures, their synthesis involved a two stage process; produc

Abstract:

The work of this thesis focuses on three perovskite-based compounds: YSr2Cu3−xCoxO7+δ cuprates, Gd2BaCo2O5+δ related phases and Sr2SnO4 Ruddlesden-Popper structures. Both YSr2Cu3−xCoxO7+δ and Gd2BaCo2O5+δ are cathode material candidates for solid oxide fuel cells (SOFCs). Doping of Sr2SnO4 aims to enhance the ionic conductivity of the parent phase and explore the phases as a potential SOFCs electrolyte material. The cobalt content in the layered perovskite YSr2Cu3−xCoxO7+δ has been increased to a maximum of x = 1.3. A slight excess of strontium was required for phase purity in these phases, yi

Mould flux for the continuous casting process is a major concern for the steelmaking industry.

Abstract:

碩士<br>長庚大學<br>電子工程學研究所<br>97<br>In this thesis, we reported on structural and electrical characteristic of high-k thulium oxide (Tm2O3), tulium titanium oxide (Tm2Ti2O7), ytterbium titanium oxide (Yb2TiO5) and holmium titanium oxide (HoTiO5) the metal-oxide-semiconductor capacitance gate dielectrics by reactive RF sputtering. Effect of titanium content in thulium oxide, ytterbium oxide and holmium oxide of the gate dielectrics with post deposition O2 annealing treatment on the crystallization temperature, leakage current, dielectric constant, and interface trap density. Compared to Tm2O3, Tm2
