  • Defect Mechanisms in Bismuth-based Perovskites

    Creator:
    Kumar, Nitish
    Abstract:
    The aim of this research is to develop a fundamental understanding of the dominant defect species and the relevant defect equilibrium conditions for bismuth-containing perovskites to help guide the development of these materials for emerging applications. This is of paramount importance for many demanding applications, because ultimately the defect equilibria...

  • 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...

  • Synthesis and characterization of Pb(Zr,Ti)O₃ thin films for microelectromechanical systems

    Creator:
    Brookshire, Kirsten L.
    Abstract:
    Pb(Zr,Ti)O₃ (PZT) is a very attractive material for use in piezoelectric-based microelectromechanical systems (MEMS) due to its high piezoelectric coefficients and ability for large displacements with relatively low applied fields (as compared to electrostatic-based MEMS). The piezoelectric effect is strongly anisotropic, thus it is very desirable to control the crystallographic...
