Abstract:

This thesis describes the growth of bismuth oxide (Bi2O3) and multiferroic bismuth ferrite (BiFeO3) films via chemical vapour deposition (CVD). The synthesis of a range of bismuth(III) β-diketonate complexes was carried out via a ligand-exchange reaction between [Bi(N(SiMe3)2)3] and the respective free ligand, and crystal structures of [Bi(dbm)3]2 and [Bi(acac)3] are reported. The decomposition of these complexes was studied via DSC-TGA to assess their potential as single-source precursors to Bi2O3, and the mass transport characteristics of the volatile complexes [Bi(mmp)3], [Bi(thd)3] and [Bi

Abstract:

Cyclic voltammetry experiments were performed to compare the electrodeposition characteristics of bismuth on ruthenium. Two types of electrodes were used for comparison: a Ru shot electrode (polycrystalline) and a thin film of radio-frequency sputtered Ru on a Ti/Si(100) support. Experiments were performed in 1mM Bi(NO3)3/0.5M H2SO4 with switching potentials between -0.25 and 0.55V (vs. KCl sat. Ag/AgCl) and a 20mV/s scan rate. Grazing incidence x-ray diffraction (GIXRD) determined the freshly prepared thin film electrode was hexagonally close-packed. After thermally oxidizing at 600°C for 20

Abstract:

Bismuth oxide based electrolytes are well known for their high oxide ion conductivity at intermediate temperatures (300-700C). Indeed, the defect fluorite structured -phase of Bi2O3 shows the highest known oxide ion conductivity of any material. Unfortunately this phase is only stable above 730C and much research has been carried out on stabilising this phase to lower temperatures through solid solution formation with other oxides. The work described in this thesis examines the structure-conductivity relationships in several substituted bismuth oxide systems. The effects of Nb5+, Y3+ and Pb

For the first time, the heterodyned fitting analysis technique shows that the field profiles on the ab basal planes of single crystal Bi2212 are symmetric in all experimental fields 1.0--7.0 T and at all experimental temperatures 2.0-90.0 K. The muon spin relaxation rates due to the mixed state of Bi2212 were found to increase linearly from 0 mus-1 at the transition temperature, 90.0 K, to about 1.0 mus -1 at the low

碩士<br>國立東華大學<br>材料科學與工程學系<br>101<br>A vapor transport process has been used to synthesize bismuth oxide nanowires.In the process , bismuth metal was used as source material , Ar and O2 were used as carrier gases with contrlled O2/Ar ratio. We have successfully synthesized one-dimensional bismuth oxide nanostructures (α-Bi2O3) on both silicon (001) and sapphire (0001) substrates by a simple vapor transport method. The morphologies, crystal structures, chemical compositons, and optical properties of the as-synthesized α-Bi2O3 nanostructures were characterized by using X-ray diffraction (XRD) , f

Abstract:

Oxide nanostrucures show very strong size-dependent changes in their thermal and chemical stability and reactivity. The total energy of nanoparticles (high surface-to-volume ratio) is increased due to the imperfect bonding structure of their surface-affected atoms. This leads to the shifts in the mentioned properties. While this relationship is valid for any kind of inorganic material the degree of these changes depends on the bond-strength and bond-nature of the material at the surface: The higher the surface energy the stronger the size-dependence. These thoughts are demonstrated here by ex

Abstract:

The thesis entitled “Variants of Complex Bismuth and Zirconium Oxides: Structure-Property Correlation Studies” consists of five chapters. A short introductory note outlines the synthetic procedures, characterization techniques and evaluated properties such as photocatalysis, second harmonic generation, ionic conductivity and thermal expansion in these materials. Chapter 1 deals with a new solid solution Pb3-xBi2x/3V2O8 (0.20 ≤ x ≤ 0.50), stabilizing the high temperature γ form of Pb3V2O8 in the system Pb3V2O8−BiVO4. Single-crystals of the composition x = 0.50 were grown and the structur
