  • A study of ZnS:Mn electroluminescent phosphors grown by halide transport chemical vapor deposition

    Creator:
    Chen, Chia-Jen
    Abstract:
    A low pressure halide transport chemical vapor deposition (HTCVD) system to grow ZnS:Mn electroluminescent phosphors is characterized. Reactor parameters such as gas composition, gas flow rate, and source and substrate temperature are investigated. Crystal structure is investigated using x-ray diffraction, electron spin resonance, and transmission electron microscopy. Chemical characterization includes...

  • Investigation of Magnesium Dioxybenzenedicarboxylate (Mg-DOBDC) Thin-film Deposition onto Modified Glass Substrates

    Creator:
    Haning, Evan J.
    Abstract:
    Metal-Organic Frameworks (MOFs) are crystalline compounds formed from reacting a metal ion with an organic ligand. They represent a promising new avenue in materials science for gas separations and storage. Certain MOFs, in particular Mg-MOF-74, have shown a strong affinity for the capture of CO2. This project investigated a known...

  • Characterization of CoGe Thin Films and Powders

    Creator:
    Pfau, Andrew James
    Abstract:
    Cobalt germanides have been widely studied as semiconductor contact materials, but recent theoretical studies suggest that they may also be excellent catalysts for methane steam reforming with stabilities and activities comparable to noble metal catalysts. In order to study the catalytic activity of cobalt germanides, it is critical to first...

  • New luminescent materials and high-performance solution-processed oxide thin films

    Creator:
    Jiang, Kai
    Abstract:
    Crystals of an incongruent-melting compound, Ba₃MgSi₂O₈, were grown by the flux method and its structure was determined by single crystal X-ray diffraction methods. Ba₃MgSi₂O₈ crystallizes in trigonal space group P-3[bar]m1 with a = 5.6123(3) Å, c = 7.2667(9) Å and Z = 1. Eu²⁺ ions prefer one crystallographic Ba site...

  • Functional materials for advanced energy and electronic devices

    Creator:
    Flynn, Brendan T.
    Abstract:
    Advances in energy technologies and electronics have typically occurred through either heightened performance or cost reduction. This dissertation explores both routes through a series of fundamental material studies that may contribute to the enabling of next generation devices. Solution based syntheses and deposition of chemical products offer a low cost...

  • Synthesis and study of oxides and chalcogenides : thin films and crystals

    Creator:
    Park, Sangmoon
    Abstract:
    Several types of solid-state inorganic materials are prepared and characterized. By using the SILAR (Successive Ionic Layer Adsorption and Reaction) deposition method in conjunction with hydrothermal dehydration both low-temperature deposition and crystallization of oxide thin films are achieved. Various aspects of new transparent p-type materials are studied by examining both...

  • 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...

  • Chemical Solution Deposition and Advanced Characterization of Pb-free, Bi-based, Piezoelectric Thin Films

    Creator:
    Mason, Ashley D.
    Abstract:
    Piezoelectric materials convert mechanical strain into a dielectric displacement, as well as the converse, allowing these materials to be used as sensors, actuators, and transducers. Currently, lead zirconate titanate (PZT) is the primary material used in these applications. Due to environmental toxicity and safety concerns associated with Pb, development of...
