  • Investigation of the dimensional stability of an ultra-thin film gas/liquid contactor

    Creator:
    Peterson, Jerrod P.
    Abstract:
    The use of a permeable membrane to mechanically constrain a film of water with an area of 12 cm² and a thickness of 150 μm in a gas/liquid contactor was investigated. The membrane separated the vapor and liquid phases, and a stiffener plate made from a gas-permeable material was used...

  • Manufacture and characterization of novel ACTFEL materials and devices

    Creator:
    Bender, Jeffrey P.
    Abstract:
    The aim of this dissertation is to develop non-traditional approaches to alternating-current thin-film electroluminescent (ACTFEL) device fabrication. ACTFEL technology suffers from a lack of adequately bright and efficient primary-color phosphors and cannot presently compete in the low-cost display market. Therefore the research presented in this dissertation focuses on an exploration...

  • Electro-optic characterization of SrS-based alternating current thin-film electroluminescent devices

    Creator:
    Nevers, Corey A.
    Abstract:
    Two methods of electro-optically characterizing alternating-current thin-film electroluminescent (ACTFEL) devices are investigated: photo-induced transferred charge (PIQ) and luminescence (PIL), and subthreshold voltage-induced transferred charge (VIQ) techniques. Both techniques provide information related to traps within the phosphor layer. PIQ/PIL experiments monitor the transport of electrons and holes across the phosphor layer...

  • Electro-optical characterization of SrS:Ce, SrS:Cu, and SrS:Cu,Ag alternating-current thin-film electroluminescent devices

    Creator:
    Grudzinsky, Arkady S.
    Abstract:
    The purpose of this thesis is to contribute to the understanding of SrS-based alternating-current thin-film electroluminescent (ACTFEL) device operation. Three main accomplishments serving this purpose are presented in this thesis. First, two new methods are developed for estimation of insulator capacitance in ACTFEL devices possessing a large amount of dynamic...

  • Electrically tunable thin-film inductors based on synthetic antiferromagnet cores

    Creator:
    An, Na
    Abstract:
    The objective of this research is to demonstrate the feasibility of implementing electrically tunable on-chip inductors based on synthetic antiferromagnet (SAF) cores. This thin film magnetic core is made of a magnetic bi-layer antiferromagnetically coupled through a nonmagnetic spacer layer. An energy model is developed to investigate the magnetic behavior...

  • ACTFEL device simulation with impact ionization using a two-sheet charge model

    Creator:
    Bouchard, Anthony F.
    Abstract:
    The main achievement of this thesis is the development of a two-sheet charge simulation model with space charge creation by trap-to-band impact ionization to describe the electrical characteristics of alternating-current thin-film electroluminescent (ACTFEL) devices. The two-sheet charge model localizes all of the space charge in the phosphor region of an...

  • Inorganic thin-film solar cells

    Creator:
    Spies, Jack Alexander
    Abstract:
    The primary objective of this thesis is to explore new absorber and p-type window layer materials for thin-film solar cell applications. A new thin-film electron beam deposition system has been installed, is now operational, and has been used to deposit several types of solar cell absorber layers. Material investigations include...

  • Ferroelectric thin film development

    Creator:
    Harman, Taran V.
    Abstract:
    The long-term goal of the research project initiated with this thesis is the development of lead-free, fully-transparent ferroelectric devices, such as ferroelectric capacitors or ferroelectric-gate field-effect transistors. Ferroelectric materials exhibit spontaneous polarization with the application of an external electric field, which is persistent upon removal of the applied field, and...

  • Metal-Organic Framework Thin Films: The Synthesis and The Application

    Creator:
    Zhang, Yujing
    Abstract:
    Metal-organic frameworks (MOFs) have gained increasing attention due to their promising applications (e.g., gas storage/separations, and catalysis) as nanoporous materials stemming from generally ultrahigh porosities and surface areas. Recently, research has shifted to synthesize MOF thin films and micropatterns that enable new applications (e.g., optoelectronics, smart coatings, and sensors). In...

  • 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...
