  • Development of new high-temperature piezoelectric perovskite ceramics

    Creator:
    Ansell, Troy Youngmin
    Abstract:
    Lead zirconate titanate (PZT) is the dominant ferroelectric material in the market due to its excellent piezoelectric properties, relatively high Curie transition temperature (T[subscript C]), low cost, etc. However, because of emerging applications with requirements for high temperature (T[subscript C] > 400 °C) ferroelectrics, researchers are increasingly looking at alternative...

  • Understanding of Ferroelectric to Relaxor Phenomenon in Bismuth-based Perovskite

    Creator:
    Gupta, Sanu K.
    Abstract:
    It has been well established that ferroelectric to relaxor crossover in piezoelectric ceramics exhibit promising electromechanical and dielectric properties over a wide temperature range, applying sensors and actuators transducers and such. A plethora of research has reported giant strain in various lead-free piezoelectric ceramics and attributed the reasoning to the...

  • 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...
