  • Towards Pactive (Passive + Active) Sensing for Security Applications

    Creator:
    Menon, Arya
    Abstract:
    Increasing threats of terrorism and contraband smuggling have led to a growing interest in millimeter wave/ THz security sensors. Recently, systems combining active and passive sensing into one unit have been proposed where the active mode provides information on range and reflectivity, and the passive mode complements the active by...

  • Wireless Microwave Sensing in Environmental and Biomedical Applications

    Creator:
    Uluer, Ismail Hakki
    Abstract:
    This dissertation studies two different wireless microwave sensing applications in the subjects of environmental monitoring and biomedical devices. The environmental sensing application presents a design of novel wireless sensor node configurations. These nodes are intended to be used specifically in a built environment of railroad track ballast for its health...

  • Electo-optic characterization of ZnS:Tb ACTFEL devices for probing the hot electron distribution

    Creator:
    Streicher, Keone R.
    Abstract:
    In this report, the optical characteristics of ZnS:Tb AC driven thin-film electroluminescent devices are evaluated. Luminescence at low and room temperature under a constant phosphor field is recorded in order to probe the hot electron energy distribution. Samples fabricated by atomic layer epitaxy and by sputter deposition are investigated and...

  • Distributed temperature sensing with neodymium-doped optical fiber

    Creator:
    Lounsbury, Jimson S.
    Abstract:
    Polymer electrolyte membrane (PEM) fuel cells are being studied for use as high efficiency power plants in alternative fuel vehicles. To maintain high efficiency the operating temperatures of the membranes in these fuel cells must be closely monitored and controlled. However, the environment inside of the fuel cell is not...

  • The analysis and synthesis of a parallel sorting engine

    Creator:
    Ahn, Byoungchul
    Abstract:
    This thesis is concerned with the development of a unique parallel sort-merge system suitable for implementation in VLSI. Two new sorting subsystems, a high performance VLSI sorter and a four-way merger, were also realized during the development process. In addition, the analysis of several existing parallel sorting architectures and algorithms...

  • Contact resistance and stability assessment of oxide-based thin film transistors

    Creator:
    Hung, Celia M.
    Abstract:
    This thesis focuses on two aspects of oxide-based thin-film transistors (TFTs), contact resistance and instability assessment. First, determination of the contact resistance of indium tin oxide (ITO) on two wide-band gap semiconductors, zinc oxide (ZnO) and indium gallium oxide (IGO), is attempted and the effects of contact resistance on device...

  • Development of acoustic transducers for use in the parametric pumping of spin waves

    Creator:
    Gross, Jonah M.
    Abstract:
    The work detailed here is the development of simulations and fabrication techniques used for the construction of thin-film acoustic transducers for use in the parametric pumping of spin waves. The Mason Model, a 1-D equivalent circuit simulating the responses of multilayer acoustic transducers, is implemented using ABCD-parameters in MATLAB to...

  • Design and analysis techniques for nano-joule ADCs and sampling linearity

    Creator:
    Brown, Thomas (Thomas William)
    Abstract:
    Two aspects of ADC system performance are addressed in this work. First, the combination of the ADC and its associated reference are co-designed for an energy constrained remote sensing system. Second, sampling linearity is mathematically analyzed as a function of frequency to provide enhanced understanding into an ADC's requisite sampling...

  • Atomic Layer Deposition of Multi-Insulator Metal-Insulator-Metal Capacitors

    Creator:
    Austin, Dustin Z.
    Abstract:
    Back end of line (BEOL) metal-insulator-metal capacitors (MIMCAPs) have become a core passive component in modern integrated circuits. International Technology Roadmap for Semiconductors (ITRS) projections for scaling of analog/mixed-signal MIMCAP applications require simultaneously increasing capacitance density while maintaining low leakage current density and low voltage nonlinearity (characterized by the quadratic...
