  • Fabrication and characterization of ACTFEL devices

    Creator:
    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...

  • Development of high efficiency solar absorbers

    Creator:
    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....

  • Development of zinc tin oxide-based transparent thin-film transistors

    Creator:
    Chiang, Hai Q.
    Abstract:
    The focus of this thesis involves development of highly transparent, n-channel, accumulation- mode thin-film transistors employing a zinc tin oxide (ZTO) channel layer. ZTO-based transparent thin-film transistors (TTFTs) show improved device performance compared to ZnO-based TTFTs. An estimated peak effective mobility for these devices as high as ~100 cm² V⁻¹sec⁻¹...

  • 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...

  • 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...

  • Instability and temperature-dependence assessment of IGZO TFTs

    Creator:
    Hoshino, Ken
    Abstract:
    Amorphous oxide semiconductors (AOSs) are of great current interest for thin-film transistor (TFT) channel layer applications. In particular, indium gallium zinc oxide (IGZO) is under intense development for commercial applications because of its demonstrated high performance at low processing temperatures. The objective of the research presented in this thesis is...

  • SPICE modeling of ACTFEL devices and OLEDs

    Creator:
    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,...

    Abstract:
    In this thesis steady-state (i.e. steady-state with respect to the applied voltage waveform) transient current-transient voltage [i(t)-v(t)], transient brightness-transient current [b(t)-i(t)], transient brightness-transient voltage [b(t)-v(t)], transient current [i(t)], transient brightness [b(t)], and detrapped charge analysis are introduced as novel organic light emitting device (OLED) characterization methods. These analysis methods involve...

  • Discrete trap modeling of thin-film transistors

    Creator:
    Yerubandi, Ganesh Chakravarthy
    Abstract:
    A discrete trap model is developed and employed for elucidation of thin-film transistor (TFT) device physics trends. An attractive feature of this model is that only two model parameters are required, the trap energy depth, E[subscript T], and the trap density, N[subscript T]. The most relevant trends occur when E[subscript...
