  • An n-sheet, state-space ACTFEL device model

    Creator:
    Hitt, John C.
    Abstract:
    The objective of the research presented in this thesis is to develop, implement, and demonstrate the utility of an n-sheet, state-space alternating-current thin-film electroluminescent (ACTFEL) device model. In this model, the phosphor layer is discretized into n + 1 layers, with band-to-band impact ionization, space charge creation/ annihilation, and luminescent...

  • 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...

  • 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...

  • 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...

  • 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...

  • Growth, Characterization and Applications of Zinc Sulfide Thin Films by Solution-Based Processes

    Creator:
    Chiu, Dick
    Abstract:
    Zinc Sulfide (ZnS) thin film, with a wide band gap, has been used for many applications, such as buffer layer for CIGS solar cells, light emitting diodes and thin film electroluminescent devices. In this work, ZnS thin films were prepared using two different deposition processes. In the first method, ZnS...

  • Growth, characterizations and applications of copper sulfide thin films by solution-based processes

    Creator:
    Vas-Umnuay, Paravee
    Abstract:
    Copper sulfides (Cu[subscript x]S) are compound semiconductor materials that exhibit considerable optical and electrical properties varying significantly as a function of the composition. Copper sulfide thin films can be used in many applications, such as solar control coatings, solar cells, photothermal conversion of solar energy, electroconductive coatings, and microwave shielding...

  • 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...
