Tuning Functional Properties of Pyrochlore and Related Oxides via Cation and Anion Substitutions

Creator:

Giampaoli, Gabriella C. S.

Abstract:

Inorganic structures play an important role in materials due to their versatility and diversity. A complete understanding of the structure of a material is vital to enhance the creation of new materials that fill voids in research. The rational design of these compounds is driven by the exploitation of structure-property...

Fabrication and geometrical characterization of metal and metal-dielectric composite periodic nanostructures

Creator:

Bhowmik, Siddhartha

Abstract:

Periodic metal and metal-dielectric composite nanostructures have been of interest from the field of plasmonics and metamaterial fabrication. In order to exploit the behavior of these unique materials in the visible region of the optical spectrum, these structures need to be significantly shorter than the wavelength of response, and hence...

Structure and piezoelectric properties of lead-free bismuth-based perovskite solid solutions

Creator:

Huang, Chien-Chih

Abstract:

A new group of lead free piezoelectric perovskite solid solutions, (1-x)Bi(B'B")O₃-xABO₃, were obtained via solid-state processing techniques. The solubility of unstable perovskite Bi(B'B")O₃ compounds into stable perovskite compounds was found to be related to the tolerance factor of the ABO₃ perovskite endmembers. The morphotropic phase boundary (MBP) in perovskite solid...
