  • Distributed Logic Memory computer for process control

    Creator:
    Smathers, John Edward
    Abstract:
    An instruction set and programming examples are described for a Distributed Logic Memory computer organization. The computer is designed to take advantage of the economies of very large-scale circuit integration. In addition, the computer can grow in an orderly way. As it grows there is increased parallelism possible so that...

  • Digital simulation of a self-excited cumulative compound direct-current generator with variable load

    Creator:
    Maraqa, Abdel Muti
    Abstract:
    This thesis develops a simulation model for a cumulative connected compound direct-current generator to varify the operation of this machine under conditions of slowly and rapidly changing loads. The application of this simulation method will contribute to more exact modeling of power system components. The accuracy gained is in the...

  • Hybrid, high speed fault detection based on instantaneous line voltages

    Creator:
    Ramchandani, Hiranand Balchand
    Abstract:
    This fault detection scheme is based on sampling the instantaneous phase voltages and checking their sum and magnitude against a specified voltage. Faults on the system cause unbalances and distortion of the phase voltages and currents. The currents and voltages change in magnitude and/or phase position with respect to the...

  • Atomic Layer Processing for Next-Generation Microelectronic Materials

    Creator:
    Holden, Konner E. K.
    Abstract:
    Atomic layer deposition (ALD) is an enabling technique for many new micro- and nanoscale technologies. The self-limiting surface chemical reactions by which ALD fundamentally operates give rise to uniquely high precision (atomic) control over deposited film thickness, uniformity over large areas, and conformality over complex and extreme topographies. One such...

  • Investigation of Energy Barrier Heights within Metal-insulator-metal Devices via Internal Photoemission Spectroscopy

    Creator:
    Jenkins, Melanie A.
    Abstract:
    Metal-insulator-metal (MIM) and dual-insulator MIM (MIIM) devices are used in rectennas, hot-electron transistors, single electron transistors, resistive random access memory (RRAM), and capacitors. The performance of these devices relies heavily on the energy barrier height at each metal-insulator interface. Thus, determination of the in-situ electron energy barrier at each interface...

  • 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...

  • Development and Applications of Oxide Thin Films using Atomic Layer Deposition and Prompt Inorganic Condensation

    Creator:
    Smith, Sean Weston
    Abstract:
    In the first part of this work, thin films of Al₂O₃ deposited via atomic layer deposition (ALD) are demonstrated to improve the thermal stability of cellulose nanocrystal (CNC) aerogels. ALD is a chemical vapor deposition (CVD) like method in which sequential precursor exposures and self-limited surface reactions produce a conformal...

  • Assessment of High Mobility Oxide Thin-Film Transistors

    Creator:
    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...

  • 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...
