A microscopic study of the interaction between aliovalent dopants and native defects in group IV oxides : indium and cadmium in ceria and zirconia

Creator:

Zacate, Matthew O.

Abstract:

In order to understand better the defect structure and dynamics associated with lower valent dopants complexed with native defects in group IV oxides, In/Cd perturbed angular correlation spectroscopy was performed in ceria and zirconia. Examining the orientation symmetry axis of defects in ceria single crystals at low temperature has allowed...

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...
