  • Development of Temperature Stable Dielectric Materials Based on Lead Bismuth Perovskite Solid Solutions

    Creator:
    Colton, Zachary D.
    Abstract:
    High energy density ceramic capacitors with temperature stable permittivity across -150°C to 300°C are desired for a wide variety of electronic devices. Traditional dielectrics such as barium titanate provide a high permittivity but that permittivity is strongly temperature dependent over this specified temperature range. The goal of this work is...

  • Development of Temperature-Stable Relaxor Dielectrics for High Energy Density Capacitor Applications

    Creator:
    McCue, Connor
    Abstract:
    High performance dielectric materials are needed for high power SiC- or GaN-based electronics which combine the best features of high energy density, low dielectric loss and high reliability and for advanced high-speed and high-voltage energy storage where temperature stability plays an important role in material properties. An ideal capacitor for...

  • The Conduction Properties of Heavily Acceptor Doped Lead Zirconate Titanate Ceramics

    Creator:
    Sangwan, Vyomika
    Abstract:
    Heavily acceptor doped Pb1.02Dx(Zr0.5Ti0.5)1-xO3 ceramics, where A is the dopant, were investigated in this research. Dopants studied included iron, magnesium and manganese at mole concentrations x ≤ 0.20. X-ray diffraction data along with scanning electron microscopy images revealed the solubility limits of these ceramics. All doped compositions exhibited a shift...

  • Fused Filament Fabrication of Filled Polymers for Metal Additive Manufacturing

    Creator:
    Barmore, Brenton
    Abstract:
    Additive manufacturing (AM) is a relatively new manufacturing technique that can create high complexity parts out of many materials in low volume. The fused filament fabrication (FFF) is the lowest cost AM process and is capable of producing only thermoplastic components. Powder injection molding (PIM) is a high volume low...

  • Evaluation of Materials for Use in Open-Cycle Magnetohydrodynamic Power Generation

    Creator:
    Bowen, Michael S.
    Abstract:
    Recent interest in oxy-fuel combustion for carbon capture, as well as advancements in technologies such as magnetics, materials, and computational modeling has sparked renewed interest in magnetohydrodynamic (MHD) power generation. The increased temperatures of oxy-fuel combustion versus air-fuel combustion poses a challenge in the selection of materials for plasma exposed...

  • Dissipation and wavepacket collision in carbon nanotube waveguides

    Creator:
    Saranam, Venkata Rajesh
    Abstract:
    Carbon nanotubes (CNTs) superior mechanical, electrical and thermal properties make them attractive components in nanomechanical devices. Their large aspect ratio and low density makes them ideal candidates for high frequency resonators in numerous applications including wireless communication, and mass and chemical sensors. One reason why CNTs have been slow to...

  • Amorphous metal thin films as a platform for solution processing

    Creator:
    Landau, Nicholas P.
    Abstract:
    The research presented herein represents an effort to combine the ultra-smooth surface of an amorphous metal thin film (AMTF) with a solution-processed dielectric synthesized via prompt inorganic condensation (PIC). Analysis of dielectric film quality is carried out via electrical measurements of metal-insulator-metal (MIM) diodes. Anneals at 500 and 700 °C...

  • Creating a Predictive Model of Cinder Cone Evolution in Central Oregon

    Creator:
    Das-Toke, Shyam P.
    Abstract:
    Cinder cones are useful geomorphic features for geological analysis because they generally have known initial states and follow a similar pattern of degradation as they are exposed to erosive processes. This is largely because cinder cones are produced by monogenetic eruptions. Characterizing large cinder cone fields in terms of age...

  • The optimization of thin film p-CuO/n-ZnO heterostructures for use in selective gas detection

    Creator:
    Dandeneau, Christopher S.
    Abstract:
    Since bulk p-CuO/n-ZnO heterocontacts were first proposed for gas detection, rapid development has taken place in improving the overall functionality of these structures. While bulk heterocontacts have been shown to exhibit desirable sensitivity and selectivity characteristics, these devices suffer from innate diffusion and ZnO/CuO connectivity drawbacks that limit their effective...

    Creator:
    Emerson, Morgan Rose
    Abstract:
    Electrical energy storage devices are currently the main limiting factor in many electrical devices and with the increasing demands placed on electrical power over fossil fuels, high energy density materials are essential. Previous research by Huang et al. on bulk (1-x)Bi(Zn₁/₂Ti₁/₂)O₃-xABO₃ solid solution systems led to the discovery of an...
