  • Dependence of oxygen vacancy concentration in zirconia on processing parameters and reducing conditions

    Creator:
    Lee, Theresa A.
    Abstract:
    ¹¹¹In/Cd perturbed angular correlation (PAC) gamma spectroscopy was used to study the point defect thermodynamics of tetragonal zirconia (t-zirconia). PAC can be used to measure, among other things, oxygen vacancy defect concentrations in t-zirconia. Higher than expected concentrations of oxygen vacancies in undoped samples were found using PAC. It was...

    Alves, Mauro A.
    Abstract:
    Nuclear techniques such as perturbed angular correlation (PAC) sample the hyperfine interactions of a large number of probe atoms in specific crystallographic sites. Real crystals contain static defects producing a distribution of electric field gradients (EFGs) that add to the ideal EFG of the crystal at any given probe site....
