  • Alternating-current thin-film electroluminescent device physics and modeling

    Creator:
    Douglas, Allan A.
    Abstract:
    Alternating-current thin-film electroluminescent (ACTFEL) devices are used in the formation of pixels in flat panel displays. ACTFEL flat panel displays have many advantages over other flat panel technologies. Specifically, ACTFEL panels are emissive displays, they have high brightness, wide viewing angles, and rugged construction. Although much is already known about...

  • Active matrix electroluminescent device power considerations

    Creator:
    Beck, Douglas
    Abstract:
    An active-matrix electroluminescent (AMEL) design tool has been developed for the simulation of AMEL display devices. The AMEL design tool is a software package that simulates AMEL device operation using a lumped parameter circuit model. The lumped parameter circuit model is developed primarily to address AMEL power dissipation issues. The...

  • Capacitance-voltage analysis, SPICE modeling, and aging studies of AC thin-film electroluminescent devices

    Creator:
    Davidson, James D. (James Douglas), 1960-
    Abstract:
    Alternating-current thin-film electroluminescent (ACTFEL) devices are metal-insulator-semiconductorinsulator- metal (MISIM) structures which emit light under high field, pulsed excitation. One aspect of ACTFEL operation that is not well understood is the aging of such devices with operating time. One of the primary goals of this thesis is to characterize the kinetics...

  • Thermally-stable amorphous metal thin films

    Creator:
    McGlone, John M.
    Abstract:
    Amorphous metal thin films (AMTFs) are of potential use for metal-insulator-metal (MIM) tunnel diode applications due to their ultra-smooth surfaces, a consequence of their amorphous microstructure. The objective of this thesis is to design a thermally-stable AMTF capable of maintaining MIM tunnel diode performance after a post-deposition anneal in excess...

  • 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...

  • 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...

  • 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...

  • Atomic solid state energy scale applied to novel thin-film solar absorbers

    Creator:
    Pelatt, Brian D.
    Abstract:
    The atomic solid state energy (SSE) scale is introduced as a tool for inorganic materials design. The SSE scale is obtained by assessing an average electron affinity (EA) (for a cation) or an average ionization potential (IP) (for an anion) for each atom using data from compounds having that specific...

  • Physical vapor deposition of novel thin-film solar absorbers

    Creator:
    Waters, Benjamin E.
    Abstract:
    Current leading thin-film solar cell technologies, i.e., cadmium telluride (CdTe) and copper indium gallium diselenide (CIGS), employ elements which are either toxic (Cd), or rare and/or expensive (In, Te, Ga, and Cd). The aim of this thesis is to investigate new, abundant, non-toxic p-type semiconductors for potential solar absorber application....

  • Thin-film transistors with amorphous oxide channel layers

    Creator:
    Grover, Manan S.
    Abstract:
    In recent years, a new class of high-performance thin-film transistors (TFTs) has emerged comprising amorphous oxide channel materials composed of heavy-metal cations (HMCs) with (n-1)d¹⁰ns⁰ (n ≥ 4, where 'n' refers to the row of the periodic table) electronic configuration. This thesis is devoted to the fabrication and characterization of...
