  • Crystallization Rates of AIST and Ge Thin Films by Optical and Electron Microscopy

    Creator:
    Bird, Victoriea L.
    Abstract:
    The amorphous to crystalline phase change is of great interest for the production and operation of phase change memory and germanium electronic devices. Phase change memory relies on the ability to differentiate between differences in optical or electrical properties between the amorphous and crystalline phases of a single material. Amorphous...

  • Solution-based deposition of functional thin films : development of a glucose biosensor and thermal processing of CZTS nanoparticle films

    Creator:
    Durgan, Christopher J.
    Abstract:
    The development of solution-based methods for deposition of different thin film material is presented as an alternative to high cost vacuum-based methods. For certain materials, vacuum techniques are unsuitable for processing. Additionally, vacuum-based processes present high capital costs associated with equipment, and slow processing times. Atmospheric pressure solution based techniques...

  • Study of Interphase in Polylactic Acid and Cellulose Nanocrystal Composite Films

    Creator:
    Rao, Pratish Ramesh
    Abstract:
    Polylactic acid (PLA), a renewable material, is used widely in a variety of commercial and specialty applications. However, certain limitations such as high temperature stability and brittleness limit its applicability. This problem is addressed by reinforcing PLA with a variety of materials but the process gives rise to different issues...

  • Fabrication of a flexible glucose sensing catheter for human implantation

    Creator:
    Matthews, David J.
    Abstract:
    Flexible electronics processing techniques were applied to integrate a glucose sensor with a hormone-delivery catheter in order to create a cheap and minimally invasive method for patients with type 1 diabetes to continually monitor and control their blood sugar levels. Ultimately, this work intends to move toward the development of...

  • 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...

  • 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...

  • Growth and characterization of the p-type semiconductors SnS and BiCuOSe

    Creator:
    Francis, Jason
    Abstract:
    BiCuOSe and SnS are layered, moderate band gap (ε[subscript G] ≈ 1 eV) semiconductors that exhibit intrinsic p type conductivity. Doping of BiCuOSe with Ca results in a slight expansion of the lattice and an increase of the hole concentration from 10¹⁸ cm⁻³ to greater than 10²⁰ cm⁻³. The large...

  • 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...

  • 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...
