  • 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...

  • Synthesis and characterization of aluminum oxide based materials - from molecule to device

    Creator:
    Wang, Wei
    Abstract:
    A scalable synthesis of the "flat" tridecameric inorganic cluster [Al₁₃(μ₃-OH)₆(μ-OH)₁₈(H₂O)₂₄]¹⁵⁺ has been realized by treating an aqueous aluminum nitrate solution with zinc-metal powder at room temperature. Single crystals and polycrystalline samples are readily obtained in yields exceeding 55% relative to the starting reagent Al(NO₃)₃. Products have been characterized by X-ray...

  • On the Properties and Characteristics of Solution Processed Hafnium Based Thin-Films from Aqueous Precursors

    Creator:
    Decker, Shawn R.
    Abstract:
    Aqueous hydroxo Hf nanoclusters enable studies to identify and codify steps in the deposition of Hf-based oxide thin films from solution precursors. HfOCl2 reacts with combinations of H2O2(aq), acids, and TMAH to produce polymetal species at high pH and low pH. X-ray scattering and spectroscopic methods reveal the nature of...

  • Wide band gap semiconductors and insulators : synthesis, processing and characterization

    Creator:
    Hersh, Peter A.
    Abstract:
    The work presented here is focused on applying basic principles of solid-state chemistry to the study and development of new wide band-gap semiconductors and insulators for photovoltaic and electronic-device applications. Analysis of crystal structure, band structure, optical band gap, morphology and transport properties provides fundamental insight into materials performance as...

  • Direct patterning of solution deposited metal oxides

    Creator:
    Stowers, Jason K.
    Abstract:
    Patterning of metal oxides typically involves a multi step process, involving depositing a resist, patterning that resist with some form of lithography, etching the oxide through the resist, and finally removing. This process can be simplified if the resist is removed and replaced with a metal oxide that can be...

  • 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...
