博士<br>國立臺灣大學<br>材料科學與工程學研究所<br>95<br>Multilayered ceramic capacitors (MLCCs) composing BaTiO3 based dielectric and metallic inner electrodes are one the most important passive components. The electrodes materials such as Ni or Cu are widely used for reducing the cost of MLCCs. These base-metal electrodes (BME) capacitors have to be fired in a reducing atmosphere to avoid the oxidation of metals. Many approaches have been reported to maintain the insulation resistance of BaTiO3 based dielectrics even when they are sintered in low oxygen partial pressure. In the present study, the Ni particles a

According to the Band Transport model, photorefraction results from absorption at impurity level inside crystals. Thus an understanding of impurity levels within a photorefractive crystal will facilitate further optimization of imputity doping as well as further understanding of photorefraction. However, at room temperature most impurity levels are broadband and may overlap with another impurity level spectrum. Thus it requires lowering he temperature i

Crystalline phases were analysed by XRD. Attention has been paid to the analysis of the corresponding sintered microstructure by adopting scanning and transmission electron microcopy. Reducing sintering was in the low oxygen partial pressure, so as to dominate the oxygen-deficient. According to the defect chemistry, the purpose of acceptor-doping was the same as reducing sintering. We look out for phenomena w

We use Calcium to replace Barium and Titanium in 2x2x1 superlattice to simulate 0.25 concentrational doping.

碩士<br>國立中山大學<br>電機工程學系<br>87<br>Recently, there has been increasing demand for high dielectric material to replace SiO2 for high-density dynamic random access memories with very large scale integration. Among many materials, the ferroelectric material of BaTiO3 has been attracted for this application. In addition, the preparation of high quality BaTiO3 thin films is essential for various devices. The deposition of BaTiO3 on (100) silicon is studied by MOCVD with Ba(DPM)2 and Ti(i-OC3H7)4 used as the Ti and Ba MO sources, respectively. The deposition was performed in a cold wall hori

碩士<br>國立臺灣大學<br>材料科學與工程學研究所<br>96<br>Abstract The properties of ceramic-metal composites exhibit significant change in the neighborhood of percolation threshold, for examples: the dielectric constant increases rapidly and the resistance decreases abruptly. In the present study, two specimen series, BaTiO3/Ni(NO3)2 and BaTiO3/Ni systems are prepared by sintering in N2. The BaTiO3/Ni composites are obtained. The effect of Ni content on the microstructure and the dielectric properties of Ni-doped BaTiO3 are investigated. The experimental results show that the microstructure of BaTiO3 spe
