  • Manufacture and characterization of novel ACTFEL materials and devices

    Creatore:
    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...

  • Assessment of High Mobility Oxide Thin-Film Transistors

    Creatore:
    Stewart, Kevin A.
    Abstract:
    The trend towards higher resolution, faster refresh rate active-matrix liquid-crystal displays (AMLCDs) as well as the emergence of active-matrix organic light-emitting diode (AMOLED) displays is driving the demand for amorphous oxide semiconductor thin-film transistors (AOS TFTs) with higher mobility. A physics-based model for carrier transport in an amorphous semiconductor is...

  • Design, fabrication, and testing of inhomogeneous dielectrics

    Creatore:
    Lim, Sungkyoo
    Abstract:
    In this thesis the concept of inhomogeneous dielectrics is demonstrated for various optical coating applications. Compositionally-varying silicon oxynitride (SiON) dielectric layers, with the refractive index varying as a function of position, are grown by computer-controlled plasma-enhanced chemical vapor deposition (PECVD) using silane, nitrogen, and nitrous oxide reactant gases. Compositionally graded...

  • Fabrication and characterization of ACTFEL devices

    Creatore:
    Keir, Paul D.
    Abstract:
    The goal of this thesis is the identification and synthesis of high-luminance, primary color alternating-current thin-film electroluminescent (ACTFEL) devices. Special attention is paid to the synthesis of primary color green ACTFEL devices because of the lack of an adequate primary green ACTFEL phosphor and the dominance of green wavelengths in...

  • SPICE modeling of ACTFEL devices and OLEDs

    Creatore:
    Bender, Jeffrey P.
    Abstract:
    The achievements of this thesis are the development of several models for the SPICE (Simulation Program with Integrated Circuit Emphasis) simulation of alternating-current thin-film electroluminescent (ACTFEL) devices, organic light-emitting devices (OLEDs), and polymer light-emitting devices (PLEDs). First, an ACTFEL model based on the built-in HSPICE Fowler-Nordheim tunneling diode is developed,...

  • Development of high efficiency solar absorbers

    Creatore:
    Ravichandran, Ram
    Abstract:
    Current cadmium telluride and copper indium gallium diselenide thin-film solar cells (TFSCs) utilize thick absorbers (2 - 4 μm). For efficient carrier extraction in these TFSCs, the absorber layer requires high carrier mobilities and a long minority carrier lifetime, which necessitates the use of a high purity, defect-free thin film....

  • Ferroelectric thin film development

    Creatore:
    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...

  • Amorphous oxide semiconductors in circuit applications

    Creatore:
    McFarlane, Brian Ross
    Abstract:
    The focus of this thesis is the investigation of thin-film transistors (TFTs) based on amorphous oxide semiconductors (AOSs) in two circuit applications. To date, circuits implemented with AOS-based TFTs have been primarily enhancement-enhancement inverters, ring oscillators based on these inverters operating at peak frequencies up to ~400 kHz, and two-transistor...
