  • Studies of Structurally Complex Thin Film Oxides for Electronic Materials

    Creator:
    Fast, Dylan Braucht
    Abstract:
    In this dissertation, the structure and electronic properties of multiple metal oxide thin films are characterized and presented. Prompt inorganic condensation (PIC) of metal-oxo and –hydroxo clusters was evaluated as a technique for making metal oxide clusters in two separate studies. The first focuses on the synthesis of lithium niobate...

  • 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...

  • 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...

  • Magnetic particles for selective extraction of trace analytes in microfluidic devices

    Creator:
    Tennico, Yolanda H.
    Abstract:
    The development of micro total analysis systems (µTAS), also called “lab-on-a-chip”, or microfluidic analysis systems, is presented in this dissertation. Various research areas, covering subjects from magnetic particles synthesis to novel microchip fabrication techniques, are explored to develop a lab-on-a-chip system capable of performing magnetic bead-based bioassays. These devices are...

  • New multi-functional chalcogenides for photovoltaic and thermoelectric materials

    Creator:
    Heo, Jaeseok
    Abstract:
    The subject of this PhD thesis is part of a research domain of great present interest in new semiconductor materials for photovoltaic and thermoelectric applications. This domain contains the elaboration and the study of both Cu-based chalcogenides bulk and thin-film samples, driven by materials design principles. One of the most...

  • Designing Dielectric Materials through Complex Metal Oxides

    Creator:
    Nikkel, Jason W.
    Abstract:
    This dissertation demonstrated that the electrical properties of complex oxide-based perovskite materials could be controlled through the careful modification of both material composition and structure. This was first shown through the modification of lead zirconate titanate (Pb(Zr0.52Ti0.48)O3, PZT) solid solutions with bismuth indate (BiInO3, BI) where the relative stability of...

  • A contribution to the development of wide band-gap nonlinear optical and laser materials

    Creator:
    Stone-Sundberg, Jennifer L.
    Abstract:
    The primary focus of this work is on examining structure-property relationships of interest for high-power nonlinear optical and laser crystals. An intuitive and simply illustrated method for assessing the nonlinear optical potential of structurally characterized noncentrosymmetric materials is introduced. This method is applied to materials including common quartz and tourmaline...

  • Synthesis of Intercalation Compounds and Nanocomposites of Inorganic Layered Hosts

    Creator:

    Abstract:
    Novel synthetic strategies are developed to prepare new intercalation compounds and nanocomposites with several layered hosts (NiPS₃, Na-montmorillonite, MoS₂ and MoO₃). In these products, alkali metals are ionic intercalates and linear polymers, dendrimers or amines act as co-intercalates. In addition to new synthetic approaches, new structures are identified and characterized....
