  • 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...

  • Relaxor characteristic and phase evolution of complex perovskite barium titanate bismuth zinc titanate ceramics

    Creator:
    Triamnak, Narit
    Abstract:
    Relaxor characteristic of the solid solution (1-x)BaTiO₃-(x)Bi(Zn₁/₂Ti₁/₂)O₃ (BTBZT) was investigated in this research. X-ray diffraction technique and Raman spectroscopy revealed the crystal structure of BT-BZT at various compositions. For compositions with x ≤ 0.08, the solid solutions exhibited clear tetragonal symmetry and transitioned to pseudo-cubic symmetry as the content of...

  • Development of complex perovskite dielectric ceramics for high temperature capacitor applications

    Creator:
    Raengthon, Natthaphon
    Abstract:
    Dielectric ceramics designed for capacitor applications for use in extreme environments, such as high temperatures, high voltages, or high-pressure environments, are in great demand. Existing capacitor technology fails to perform within these extreme conditions or such environments. The development of new dielectric ceramic materials for high temperature capacitor applications is...

  • Bi-based perovskite solid solutions for high energy density thin films

    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...
