  • Aqueous chemistries for oxide electronics

    Creator:
    Meyers, Stephen T.
    Abstract:
    The variegated aqueous chemistries of metal cations are applied to the design and synthesis of non-toxic solution precursors suitable for additive printing of large-area oxide electronics. Polycondensation behaviors of aqueous Al+3 and PO4 +3 are manipulated in the deposition of atomically smooth amorphous aluminum oxide phosphate (AlPO) dielectric films. AlPO...

  • Functional transition metal oxides : structure-property relationships

    Creator:
    Smith, Andrew E.
    Abstract:
    Transition metal oxides are an important class of materials for the wide variety optical, electrical, dielectric, magnetic, and thermal properties observed. Their unique structure-property relationships allow for property tuning and often provide insight into the fundamentals of chemistry. The work in this thesis was focused on the design, synthesis and...

  • The chemistry and device applications of amorphous thin-film interfaces

    Creator:
    Knutson, Christopher C.
    Abstract:
    Solid-state amorphous materials show amazing promise in thin-film electronics. The interface-to-bulk ratio of thin films makes interfacial chemistries of these systems of utmost importance. Thin films of amorphous metals, dielectrics and semiconductors have novel chemistries that are not only based upon their elemental constituent makeup, but also based upon the...

  • Precursor Chemistry and Film Structure and Properties via Solution Deposition

    Creator:
    Huang, Yu
    Abstract:
    Chemistry of preparing dense film from solution deposition is explored with several cases in this thesis. Surface dense structure, conversion at melting point, and ion exchange in aqueous solution are the main topics covered here for the thin films of aluminum oxide phosphate and tin dioxide. Thin film density, optical...

  • 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...

  • Structure-Property Relationships of Disordered Electronic Materials : From Crystalline to Amorphous

    Creator:
    Surta, Todd Wesley, Jr.
    Abstract:
    Two perovskite materials (Bi0.5(A)0.5)(Sc0.5Nb0.5)O3, where A = K+ and Na+ were synthesized phase pure for the first time. Their structures were determined by indexing synchrotron X-ray diffraction data and subsequent combined Rietveld refinement on neutron and synchrotron X-ray diffraction data revealing significant disorder on the A-sites of these materials. A...

  • Substitutional Effects on the Electromechanical Properties of Lead-free, Piezoelectric (Na₀.₅Bi₀.₅)TiO₃-BaTiO₃ (NBT-BT)

    Creator:
    McQuade, Ryan R.
    Abstract:
    This work investigates the effect of cation substitution on the properties of the lead-free, solid solution (Na₀.₅Bi₀.₅)TiO₃-BaTiO₃ (NBT-BT). Substitution into NBT-BT increases disorder and increases the relaxor ferroelectric properties. These relaxor ferroelectric materials show large piezoelectric strains that can be utilized in actuator applications. Ceramic samples were prepared using standard...

  • Cation Substitution Effects in Complex Transition Metal Oxides

    Creator:
    Duell, Brett A.
    Abstract:
    Understanding structural evolution in solids as composition changes is essential to materials properties prediction. Such structure-properties relationships are the theme of solid state chemistry. Materials scientists and chemists have utilized an abundance of simple crystal structures to enhance understanding of chemical and structural origins of properties in materials for decades....

  • Formation of hybrid supramolecular assemblies using biological molecules and transition metals

    Creator:
    Smith, Rachelle M. S.
    Abstract:
    Naturally occurring assemblies, such as DNA and proteins, utilize intermolecular forces (i.e H-bonding and van der Waals) to assemble. Utilizing these electrostatic interactions has only just started in the past five decades to be a tool used in synthetic chemistry in what is known as supramolecular chemistry. Supramolecular chemistry has...

    Abstract:
    This dissertation presents a study of structure-property relationships within 3d/4d metal oxides containing precious metals through detailed structure refinements using high-resolution neutron and X-ray diffraction data along with exploration of the resultant properties. Oxides of 4d or 5d transition metals tend to show new topological phases due to significant spin-orbit...
