  • DC/AC Stability of In-Ga-Zn-O Thin-Film Transistors

    Creator:
    Zhou, Fan
    Abstract:
    The electrical stability of amorphous indium-gallium-zinc oxide (a-IGZO) thinfilmtransistors (TFTs) is investigated for flat-panel display applications. Althoughproducts incorporating a-IGZO TFT backplanes are already commercially available,e.g., iMac with 5K retina display, technical challenges need to be addressed for nextgenerationapplications, e.g., active-matrix organic light-emitting diode displays.Device stability is one crucial issue. The...

  • Low-cost deposition methods for transparent thin-film transistors

    Creator:
    Norris, Benjamin J.
    Abstract:
    The objective of this dissertation is to introduce low-cost processing methods for the fabrication of ZnO transparent thin-film transistors (TTFTs). A novel method for depositing ZnO body layers via spin-coating of a zinc nitrate-based spin solution is presented. The processing conditions of spin-coated ZnO are optimized to produce continuous and...

  • Development of oxide semiconductors : materials, devices, and integration

    Creator:
    Chiang, Hai Q.
    Abstract:
    The aim of this dissertation is to develop oxide semiconductors by radio-frequency sputtering for thin-film transistor (TFT) applications. A variety of oxide semiconductors are used as the TFT channel layer, including indium gallium oxide (IGO), zinc tin oxide (ZTO), and indium gallium zinc oxide (IGZO). The variety of materials used...

  • 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...

  • Novel ACTFEL phosphor development

    Creator:
    Ang, Wie Ming
    Abstract:
    The goal of this thesis is to identify and to explore novel ACTFEL phosphor materials. Several important materials properties relevant to ACTFEL phosphor development are identified. All of these properties cannot be obtained simultaneously. Therefore, several key phosphor materials properties are identified as critical to the development of an ACTFEL...

  • 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...

  • Electronic Conduction Mechanisms in Insulators

    Creator:
    Chiang, Tsung-Han
    Abstract:
    The research presented herein focuses on electrical assessment of oxide thin films as insulators. The current density-electric field (J-E) characteristics of four insulators of dramatically different electrical quality are assessed in terms of their operative electronic conduction mechanisms. Conduction in the two high-quality insulators is dominated by Ohmic conduction and...

  • Fabrication and characterization of thin-film transistor materials and devices

    Creator:
    Hong, David
    Abstract:
    A class of inorganic thin-film transistor (TFT) semiconductor materials has emerged involving oxides composed of post-transitional cations with (n-1)d¹⁰ns⁰ (n≥4) electronic configurations. This thesis is devoted to the pursuit of topics involving the development of these materials for TFT applications: Deposition of zinc oxide and zinc tin oxide semiconductor layers...

  • Fabrication process assessment and negative bias illumination stress study of IGZO and ZTO TFTs

    Creator:
    Hoshino, Ken
    Abstract:
    Indium-gallium-zinc oxide (IGZO) and zinc-tin oxide (ZTO) are investigated for thin-film transistor (TFT) applications. Negative bias illumination stress (NBIS) is employed for electrical stability assessment. Unpassivated IGZO and ZTO TFTs suffer from severe NBIS instabilities. Zinc-tin-silicon oxide is found to be an effective passivation layer for IGZO and ZTO TFTs,...
